Synthesis pass · prose summary of the discoveries below

DLC1 is a focal adhesion-localized RhoGAP tumor suppressor that inactivates RhoA, RhoB, and RhoC to suppress Rho/ROCK/MLC2-mediated actomyosin contractility, cell migration, and tumorigenesis across multiple tissue types (PMID:14633684, PMID:17932950, PMID:18648664, PMID:18519636). Its GAP activity is held in check by intramolecular autoinhibition — the N-terminal region binds the RhoGAP domain in a closed monomeric conformation — which is relieved by CDK5 phosphorylation and PKA-induced dimerization, while AKT phosphorylation re-imposes autoinhibition and p120RasGAP SH3 domain binding directly occludes the catalytic arginine finger (PMID:25452387, PMID:23511482, PMID:29114068, PMID:35970859). Full tumor suppressor function requires focal adhesion recruitment through an LD-like motif that binds talin and FAK, tensin/cten SH2-domain interactions, PI(4,5)P2-mediated stimulation of GAP activity, and a RhoGAP-independent START domain–caveolin-1 interaction (PMID:21969587, PMID:17190795, PMID:19710422, PMID:22693251). In melanoma, nuclear DLC1 paradoxically functions as an oncogene by cooperating with FOXK1 to transcriptionally activate MMP9 and promote invasion independently of RhoGAP activity (PMID:32214200).

1998 DLC1 was cloned from primary hepatocellular carcinoma, encodes a 1091-amino acid protein with 86% homology to rat p122 RhoGAP, and was localized to chromosome 8p21.3-22. Loss of heterozygosity was detected in 7/16 primary HCCs and 10/11 HCC cell lines, and DLC1 mRNA was absent in 4/14 HCC cell lines, establishing it as a candidate tumor suppressor with RhoGAP homology. Representational difference analysis, LOH analysis, Northern blot, FISH chromosomal mapping Cancer research High 9605766
2003 DLC1 protein was established as a GTPase-activating protein with specific activity for RhoA and Cdc42 in an in vitro GAP activity assay. CpG island methylation in the DLC1 promoter was found in 3/7 HCC cell lines and 6/25 primary HCCs, demonstrating epigenetic silencing as a mechanism of inactivation alongside LOH.

2003 Restoration of DLC1 expression in breast carcinoma cell lines lacking endogenous DLC1 caused significant growth inhibition, reduction of colony formation, and abolished in vivo tumorigenicity in nude mice, establishing DLC1 as a bona fide tumor suppressor gene in breast cancer. cDNA transfection, colony formation assay, xenograft tumor formation in nude mice Oncogene High 12545165
2004 Restoration of DLC1 expression in hepatocellular carcinoma cell lines induced caspase-3-mediated apoptosis, inhibited cell growth and invasiveness in vitro, and reduced tumor formation in nude mice. DLC1 protein was localized to the cell cytoplasm by immunostaining. cDNA transfection, caspase-3 activity assay, immunostaining for subcellular localization, invasion assay, xenograft model Oncogene High 14647417
2004 DLC1 suppresses non-small cell lung carcinoma (NSCLC) growth and tumorigenicity. DLC1 exhibited strong GAP activity for RhoA, RhoB, and RhoC but only very limited activity for Cdc42 in vitro when assayed as full-length protein, whereas the isolated RhoGAP domain showed 5- to 20-fold enhanced activity for all four GTPases, implying autoinhibition of the full-length protein. DLC1 dramatically reduces RhoA activity at the leading edge of cellular protrusions as shown by a RhoA biosensor.

2005 Homozygous inactivation of mouse DLC1 (Arhgap7) by homologous recombination is embryonic lethal by day 10.5 post coitum, with defects in neural tube, brain, heart, and placenta. DLC1-deficient fibroblasts displayed alterations in actin filament organization and focal adhesion structure, demonstrating an essential developmental role for DLC1 GAP activity in vivo.

2006 DLC1 interacts with the SH2 domain of cten (C-terminal tensin-like) in a phosphotyrosine-independent manner. Site-directed mutagenesis identified residues on both cten and DLC1 essential for interaction. Disruption of this interaction abrogated DLC1 focal adhesion localization and eliminated tumor suppression activity; fusing these DLC1 mutants to a focal adhesion targeting sequence significantly restored tumor suppressor activity, demonstrating that focal adhesion localization mediated by cten is essential for DLC1 function. Co-immunoprecipitation, site-directed mutagenesis, immunofluorescence, focal adhesion targeting fusion constructs, colony formation assay The Journal of cell biology High 17190795
2006 DLC1 interacts with tensin2 directly in vitro and in vivo. Both proteins co-localize to punctate cytoplasmic structures and interact with endogenous caveolin-1 (a major structural component of caveolae) via caveolin-1 binding motifs present in both DLC1 and tensin2, suggesting that the DLC1-tensin2 complex acts within caveolae to regulate Rho GTPases and cytoskeletal reorganization. In vitro binding assay, co-immunoprecipitation, immunofluorescence co-localization, sequence analysis of caveolin-binding motifs Cancer research Medium 16951145
2007 DLC1 tumor suppressor activity requires cooperation between its tensin-binding activity and its RhoGAP activity. DLC1 binds tensin1 through both the tensin SH2 and PTB domains. The SH2 binding depends on a specific tyrosine (Y442) in DLC1 but is phosphotyrosine-independent—an unusual feature for SH2 binding. The Y442F mutant is diffusely cytoplasmic (not focal adhesion-localized) but retains RhoGAP activity, yet shows markedly reduced biological tumor suppressor activity, demonstrating that focal adhesion localization via tensin binding is required for full function independently of RhoGAP activity. Co-immunoprecipitation, point mutagenesis (Y442F and RhoGAP-dead mutants), immunofluorescence, Rho-GTP measurement, biological activity assays Proceedings of the National Academy of Sciences of the United States of America High 17517630
2008 DLC1 negatively regulates the Rho/ROCK/MLC2 signaling pathway in hepatocellular carcinoma. Ectopic DLC1 expression abolished Rho/ROCK-mediated stress fiber and focal adhesion formation, downregulated cortical phosphorylation of myosin light chain 2 (MLC2), and inhibited ROCK-related MYPT1 phosphorylation at Thr853. These effects were dependent on RhoGAP activity, as the DLC1 K714E RhoGAP-deficient mutant abolished them. Expression of dominant-active ROCK rescued cells from DLC1-induced cytoskeletal collapse. Ectopic expression, immunofluorescence, Western blot (MLC2 and MYPT1 phosphorylation), RhoGAP-deficient mutant (K714E), dominant-active ROCK rescue experiment PloS one High 18648664
2008 DLC1 activity is regulated by phorbol-ester-induced activation of protein kinase C and protein kinase D, which stimulates association of DLC1 with 14-3-3 adaptor proteins via phosphoserine recognition motifs involving Ser327 and Ser431. Association with 14-3-3 proteins inhibits DLC1 GAP activity and blocks DLC1 nucleocytoplasmic shuttling, likely by masking a nuclear localization sequence. Co-immunoprecipitation, in vitro GAP activity assay, site-directed mutagenesis (Ser327, Ser431), nuclear/cytoplasmic fractionation, phorbol ester treatment Journal of cell science High 19066281
2008 DLC1 localizes to focal adhesions via a 'focal adhesion-targeting (FAT) domain' (amino acids 265–459). This localization is required for DLC1-mediated morphological change (cell rounding) and regulation of cell migration and spreading. Expression of the FAT domain alone acts as a dominant negative, dissociating endogenous DLC1 from focal adhesions and reducing cell migration and spreading. DLC1 regulates actin rearrangement through down-regulation of active RhoA and Cdc42.

2008 p122/DLC1 localizes to caveolin-enriched membrane domains (caveolae) via its GAP domain, in a manner dependent on membrane cholesterol levels. Transient expression of DLC1 causes internalization of caveolin-1 and reorganizes F-actin, suggesting that DLC1 plays a role in caveolin distribution through actin cytoskeleton reorganization.

2009 The SAM domain of DLC1 (but not DLC2) binds eukaryotic elongation factor 1A1 (EF1A1), identified by protein precipitation and mass spectrometry. NMR solution structure of DLC1 SAM revealed a monomeric four-helix fold. Mutation of hydrophobic patch residues F38, L39, and F40 abolished EF1A1 interaction. DLC1 SAM facilitates EF1A1 distribution to membrane periphery/ruffles upon growth factor stimulation. The DLC1 SAM domain promotes cell migration in a GAP-independent, EF1A1-interaction-dependent manner. Protein precipitation, mass spectrometry, NMR structure determination, site-directed mutagenesis, immunofluorescence, cell migration assay Journal of cell science High 19158340
2009 DLC1 binds phosphatidylinositol-4,5-bisphosphate (PI(4,5)P2) through a polybasic region (PBR) adjacent to its RhoGAP domain. PI(4,5)P2-containing membranes stimulate DLC1 GAP activity in vitro. In cells, a DLC1 PBR mutant inactivates Rho signaling less efficiently and is severely impaired in suppressing cell spreading, directed migration, and proliferation, establishing PI(4,5)P2 as a cofactor for DLC1 activation. Lipid-binding assay, in vitro GAP activity assay with PI(4,5)P2-containing membranes, site-directed mutagenesis of PBR, cell spreading/migration/proliferation assays Molecular biology of the cell High 19710422
2009 DLC1 interacts with tensin2 through a novel phosphotyrosine-binding (PTB) domain-dependent binding site at DLC1 residues 375–385, distinct from previously identified tensin SH2 domain interactions. Removal of this PTB-binding site partially reduced RhoGAP activity and attenuated DLC1 growth-suppressive activity, while not affecting focal adhesion localization or interactions with tensin1 and cten. Co-immunoprecipitation, deletion mutagenesis, immunofluorescence, RhoGAP activity assay, growth suppression assay PloS one Medium 19440389
2010 Tensin 2 negatively regulates DLC1 to permit Rho-mediated actomyosin contraction. Tensin 2 knockdown significantly reduced the ability of human foreskin fibroblasts to contract 3D collagen gels and was associated with reduced Rho activity. This effect was reversed by co-depletion of DLC1, establishing a tensin 2 → DLC1 (inhibition) → RhoA → actomyosin contraction pathway in fibroblasts. siRNA knockdown of tensin isoforms and DLC1, 3D collagen gel contraction assay, Rho activity measurement, live-cell imaging Journal of cellular biochemistry High 20069572
2010 Protein kinase D (PKD) phosphorylates DLC1 at Ser807 within the GAP domain, as identified by mass spectrometry and validated with a phospho-Ser807-specific antibody. While Ser807 phosphorylation did not directly alter in vitro GAP activity, a Ser807Ala DLC1 mutant inhibited colony formation more potently than wild-type, indicating that PKD-mediated phosphorylation negatively regulates DLC1 cellular function. Mass spectrometry phospho-site mapping, phospho-specific antibody, in vitro GAP activity assay, colony formation assay with S807A mutant Experimental cell research Medium 21087603
2011 DLC1 contains an LD-like motif (residues 469LDDILYHV476) that binds both talin and focal adhesion kinase (FAK). This motif is necessary for DLC1 localization to focal adhesions; LD-like motif mutants are diffusely cytoplasmic but retain RhoGAP activity yet display reduced tumor suppressor activity, indicating that talin and FAK binding via this motif is required for full DLC1 tumor suppressor function independently of Rho-GTP regulation. Co-immunoprecipitation, site-directed mutagenesis (deletion and substitution mutants), immunofluorescence, Rho-GTP measurement, biological activity assays (anchorage-independent growth, tumor formation) Proceedings of the National Academy of Sciences of the United States of America High 21969587
2012 DLC1 interacts with α-catenin; their binding is mediated by DLC1 N-terminal residues 340–435 and α-catenin N-terminal residues 117–161. The DLC1–α-catenin complex reduces RhoA-GTP at the plasma membrane, associates with E-cadherin and β-catenin at adherens junctions, requires DLC1 GAP activity for membrane accumulation, and stabilizes adherens junctions. This mechanism contributes to DLC1 oncosuppressive activity in prostate carcinoma cells.

2012 DLC1 forms a complex with caveolin-1 (CAV-1), and the interaction is mapped to the DLC1 START domain. START domain mutations disrupted DLC1-CAV-1 interaction and colocalization. DLC1 with a START domain mutation failed to suppress neoplastic growth despite retaining RhoGAP activity, demonstrating that DLC1 START domain-CAV-1 interaction contributes to tumor suppression via a RhoGAP-independent mechanism. Co-immunoprecipitation, domain mapping mutagenesis, immunofluorescence, anchorage-independent growth assay, Rho-GTP measurement Cancer research High 22693251
2013 Cyclic AMP-dependent protein kinase A (PKA) phosphorylates DLC1 at Ser549, which enhances RhoGAP activity and promotes DLC1 dimerization. Ser549 phosphorylation-induced dimerization is required for enhanced tumor suppressor activity: inducible dimerization of a Ser549-deletion DLC1 rescues tumor suppressive and RhoGAP activities. This establishes PKA-induced dimerization as a novel mechanism regulating DLC1 RhoGAP activity. In vitro kinase assay, phospho-site mutagenesis, in vitro RhoGAP activity assay, co-immunoprecipitation for dimerization, in vitro and in vivo tumor suppression assays Nature communications High 23511482
2014 CDK5 kinase phosphorylates four serines in DLC1 located N-terminal to the RhoGAP domain. When unphosphorylated, this N-terminal region acts as an autoinhibitory domain that places DLC1 in a closed, inactive conformation by binding to the RhoGAP domain. CDK5 phosphorylation relieves this autoinhibition, coordinately activating DLC1 localization to focal adhesions, RhoGAP activity, and binding to tensin and talin. Inhibition of CDK5 thus inactivates DLC1's tumor suppressor function. In vitro kinase assay, mass spectrometry phospho-site identification (4 serines), intramolecular binding assay (autoinhibition domain binds RhoGAP domain), co-immunoprecipitation (tensin/talin binding), immunofluorescence, RhoGAP activity assay The Journal of cell biology High 25452387
2016 The crystal structure of the talin R8 domain bound to the DLC1 LD motif was solved, revealing that the DLC1 LD motif forms a helix that binds the four-helix bundle of talin R8 in a canonical triple-helix arrangement. The same R8 surface also binds paxillin LD1 and LD2 motifs, indicating competitive interactions. Key charged residues stabilizing R8-LD interactions were identified and their importance validated in vitro and in cells.

2017 Multiple receptor tyrosine kinase (RTK) ligands increase RhoA-GTP levels in a manner dependent on AKT activation. AKT phosphorylates three serines (S298, S329, S567) in the DLC1 N-terminal region, inducing strong intramolecular binding of this N-terminal region to the RhoGAP domain, converting DLC1 from an open, active dimer to a closed, inactive monomer, thereby reducing RhoA-GTP hydrolysis, DLC1 ligand binding, and focal adhesion colocalization. In vitro AKT kinase assay, mass spectrometry phospho-site identification, intramolecular binding assay, Rho-GTP measurement, co-immunoprecipitation, immunofluorescence, transgenic cancer model, AKT inhibitor treatment The Journal of cell biology High 29114068
2017 DLC1 is asymmetrically localized to the cytoplasm at the cell front in avian trunk neural crest cells (NCCs), where it suppresses RhoA activity, while RhoA is highly active at the cell rear. This asymmetric DLC1 localization requires its association with NEDD9. Loss of DLC1 or its asymmetric localization disrupts NCC polarity, directional delamination, and migration. SOX10 regulates DLC1 expression, and SOX9 regulates NEDD9, establishing a SOX9/SOX10–NEDD9/DLC1–RhoA regulatory axis for NCC migratory polarization. RHOA biosensor (in vivo and in vitro), siRNA/morpholino knockdown, immunofluorescence, co-immunoprecipitation (DLC1-NEDD9), in vivo neural crest delamination/migration assays in chick embryo Nature communications High 29084958
2017 DLC1 regulates endothelial cell migration and tube formation through distinct mechanisms. Silencing DLC1 enhances cell migration (through increased RhoA activity) but reduces tube formation. Further silencing of RhoA restores migration but not tube formation, while paxillin knockdown rescues both tube formation and migration. This establishes that DLC1 regulates endothelial migration through RhoA and tube formation mainly via paxillin, through independent pathways. siRNA knockdown, RhoA activity assay, cell migration assay, tube formation assay, endothelial-specific conditional knockout mice (DLC1-Tek), gel plug and aortic ring angiogenesis assays Cancer letters High 28408355
2018 Talin R8 domain unfolding under mechanical force controls DLC1 downstream signaling. Using a talin mutant resistant to force-induced unfolding of R8, DLC1 binding to folded talin suppresses RhoA-dependent cell contractility. When talin R8 is force-unfolded, DLC1 is released and RhoA activity increases, altering cell mechanics. This identifies mechanical unfolding of the talin R8 domain as a mechanotransduction mechanism that controls DLC1-RhoA signaling.

2019 The DLC1 SAM domain binds specific peptide motifs within the C2 domains of tensin-3 (TNS3) and PTEN, and this interaction relieves DLC1 autoinhibition (the intramolecular SAM–RhoGAP interaction). Cell-permeable C2-derived peptides (TAT-fused) that compete for SAM domain binding promoted DLC1 RhoGAP activity, reduced RhoA activation, and inhibited tumor cell growth and migration. A cyclic version of the TNS3-C2 peptide effectively entered cancer cells and inhibited migration. In vitro domain-domain interaction assay, peptide competition assay, cell-permeable TAT-peptide delivery, RhoA-GTP measurement, soft-agar growth assay, cell migration assay The Journal of biological chemistry High 31806702
2020 DLC1 is a direct transcriptional target of the YAP/TAZ-TEAD complex in endothelial cells. Substrate stiffening and VEGF stimuli promote DLC1 expression in a YAP/TAZ-dependent manner. DLC1 limits F-actin fiber formation, integrin-based focal adhesion lifetime, and integrin-mediated traction forces. Depletion of endothelial DLC1 perturbs cell polarization in collective migration and inhibits angiogenic sprouting; ectopic DLC1 expression restores migration and sprouting in YAP-depleted cells. Chromatin immunoprecipitation (YAP/TAZ-TEAD binding to DLC1 promoter), siRNA knockdown, constitutively active YAP expression, live-cell imaging, traction force microscopy, in vitro sprouting assay Journal of cell science High 31964713
2020 Cancer-associated point mutations in the DLC1 RhoGAP domain are deficient for RhoGAP activity and for suppressing cell migration and anchorage-independent growth (7 of 9 tested RhoGAP domain mutants). A DLC1 linker region mutant showed reduced 14-3-3 binding, while a START domain mutant showed reduced caveolin-1 binding, both with impaired tumor suppressor function despite normal RhoGAP activity, demonstrating that multiple molecular mechanisms underlie cancer-associated DLC1 inactivation. In vitro RhoGAP activity assay, co-immunoprecipitation (14-3-3, caveolin-1 binding), cell migration assay, anchorage-independent growth assay, TCGA mutational analysis Cancer research High 32606003
2020 In melanoma cells (where DLC1 is highly expressed), nuclear-localized DLC1 functions as an oncogene rather than tumor suppressor. Mass spectrometry identified FOXK1 transcription factor as a DLC1-associated nuclear protein. FOXK1 mediates translocation and retention of DLC1 in the nucleus in a RhoGAP-independent manner. DLC1 and FOXK1 cooperatively activate MMP9 transcription through FOXK1-regulated promoter occupancy, promoting melanoma invasion and metastasis. Mass spectrometry (nuclear DLC1 interactome), co-immunoprecipitation (DLC1-FOXK1), immunofluorescence (nuclear localization), RNA-seq, ChIP (FOXK1 promoter occupancy at MMP9), invasion/metastasis assays Oncogene High 32214200
2021 DLC1 protein is post-translationally destabilized by cytoplasmic EZH2 methyltransferase, leading to CUL-4A ubiquitin-dependent proteasomal degradation. KRAS knockdown reduces cytoplasmic EZH2 levels and increases DLC1 protein. Pharmacologic inhibition of EZH2, CUL-4A, or the proteasome increases DLC1 steady-state protein levels. Additional kinase inhibition of AKT and/or SRC (which directly phosphorylate DLC1) further enhances DLC1 tumor suppressor activity, producing potent tumor growth inhibition with markers of apoptosis and senescence in a DLC1-dependent manner. siRNA knockdown (EZH2, CUL-4A, KRAS), pharmacological inhibitor treatment, immunoprecipitation for methylation and ubiquitination, proteasome inhibition, DLC1-dependent tumor growth assays Nature communications High 34862367
2022 The p120RasGAP SH3 domain directly binds the DLC1 RhoGAP domain at a site partially overlapping the RhoA binding site and impinging on the catalytic arginine finger. The co-crystal structure of the p120RasGAP SH3 domain bound to DLC1 RhoGAP was solved. Mutagenesis of the interface relieves SH3-mediated inhibition of DLC1 RhoGAP activity, revealing the structural mechanism by which p120RasGAP inhibits DLC1 GAP function. X-ray co-crystallography (SH3-RhoGAP complex), in vitro RhoGAP activity assay, site-directed mutagenesis of interface residues Nature communications High 35970859
2008 DLC1 knockdown cooperates with Myc to promote hepatocellular carcinoma in a mosaic mouse model. Cells with reduced DLC1 contain increased GTP-bound RhoA. Expression of constitutively activated RhoA mimics DLC1 loss in promoting hepatocarcinogenesis. Conversely, RhoA downregulation selectively inhibits tumor growth of hepatoma cells with disabled DLC1, establishing genetic epistasis between DLC1 and RhoA in HCC development.

2016 Dlc1 knockout mouse embryonic fibroblasts completely fail to differentiate into adipocytes, but this phenotype can be rescued by inhibitors of Rho-associated kinase (ROCK) and filamentous actin (F-actin), establishing that DLC1 promotes white and brown adipocyte differentiation through suppression of the Rho-ROCK pathway. PPARγ binds to the Dlc1 gene promoter and regulates its expression during adipogenesis.

2016 DLC1 interacts with non-muscle myosin heavy chain II-A (Myh9) in multiprotein complexes identified by mass spectrometry in Dlc1-overexpressing cells, and also interacts with plectin and spectrin proteins. Dlc1 overexpression leads to increased Myh9 phosphorylation and activation of Rac1 GTPase, providing a molecular basis for Dlc1-induced cell elongation morphology.

2011 UDCA inhibits proteasomal degradation of DLC1 protein in a ubiquitin-independent manner, extending DLC1 protein half-life and reducing RhoA activity in hepatocellular carcinoma cells. Growth suppression by UDCA was reversed by DLC1 siRNA, and Rho inhibitor treatment restored reduced proliferation caused by DLC1 knockdown, placing DLC1-RhoA in the UDCA anti-proliferative pathway. Protein half-life assay (cycloheximide chase), ubiquitination immunoprecipitation, siRNA knockdown, Rho activity assay, MTS proliferation assay Oncology reports Medium 21455586
2008 TSA (trichostatin A), a histone deacetylase inhibitor, activates DLC1 promoter activity through two specific Sp1 sites at −219 and −174 relative to the transcription start site. Sp1 (but not Sp3) specifically binds these sites and enhances TSA-responsiveness. p300 coactivator is required for TSA-mediated DLC1 transcriptional activation, as p300 overexpression increased and p300 knockdown reduced TSA-induced DLC1 promoter activity. Promoter reporter assay, electrophoretic mobility shift assay (EMSA), site-directed mutagenesis of Sp1 sites, p300 overexpression and siRNA knockdown Experimental & molecular medicine Medium 19116449
