Mechanistic narrative

Synthesis pass · prose summary of the discoveries below

ARHGAP24 (FilGAP) is a Rac1-specific GTPase-activating protein that integrates RhoA/ROCK signaling with actin remodeling to enforce Rho-Rac antagonism during cell spreading, motility, and tissue morphogenesis (PMID:16862148, PMID:21911940). It is targeted to sites of membrane protrusion and force transfer by binding the 23rd Ig repeat of filamin A through its C-terminal residues, an interaction requiring dimerization of both partners; mechanical strain on the actin/FLNa network causes FilGAP to dissociate, coupling mechanotransduction to local Rac inactivation and mechanoprotection against force-induced apoptosis (PMID:19293932, PMID:19144823, PMID:21926999). ROCK phosphorylation, including at Ser402, stimulates its RacGAP activity and controls its partition between the actin cytoskeleton and cytoplasm, with dephosphorylation accompanying cell spreading on fibronectin (PMID:16862148, PMID:26359494). FilGAP localization is further directed by phosphoinositides and Arf6: its PH domain binds PIP3/PI(3,4)P2 and activated Arf6 to recruit it to the plasma membrane, cell front, and invadopodia, where it locally inactivates Rac1 to govern bleb and pseudopod formation, front-rear polarity, and ECM invasion (PMID:24526684, PMID:33710706, PMID:37482421). An EGF-driven RSK-then-GSK3 cascade phosphorylates Ser625/Ser621 to release FilGAP from actin and promote chemotactic migration, while RBM10/Fyn and AGAP1 control its peripheral and vesicular targeting (PMID:38426123, PMID:26751795, PMID:31785816). Through these activities FilGAP shapes adherens junctions, focal adhesions, and epithelial tubulogenesis downstream of Rho-ROCK (PMID:25908853, PMID:38421271), and beyond its GAP function it acts as a scaffold that recruits WWP1 to degrade PKM2 and suppress β-catenin signaling and that engages Raptor, Rictor, and Sin1 to activate mTORC1/2 (PMID:36168627, PMID:38065968). Loss of ARHGAP24 function causes familial focal segmental glomerulosclerosis through defective podocyte Rac1/PAK1 control (PMID:21911940, PMID:38421271).

2006 FilGAP (ARHGAP24) is a Rac-specific GTPase-activating protein (GAP) that binds filamin A (FLNa). FLNa targets FilGAP to sites of membrane protrusion where it antagonizes Rac in vivo. ROCK phosphorylates FilGAP, and this phosphorylation stimulates its RacGAP activity and is required for FilGAP-mediated bleb formation. Knockdown of FilGAP abrogates ROCK-dependent suppression of lamellae, establishing FilGAP as a mediator of RhoA-Rac antagonism. siRNA knockdown, dominant-negative constructs, co-immunoprecipitation, in vitro kinase assay (ROCK phosphorylation), cell spreading assay on fibronectin, live-cell imaging of blebs Nature cell biology High 16862148
2009 FilGAP interacts with the 23rd Ig repeat of filamin A (IgFLNa23) via the C-terminal 32 residues of FilGAP engaging the C and D beta-strands of IgFLNa23. Tight complex requires dimerization of both partners and a flexible hinge between FLNa repeats 23-24. FilGAP does not bind FLNa homologs FLNb or FLNc. Disease-associated FLNa mutations disrupt this binding interface, perturb cell spreading, and weaken elasticity of the FLNa/F-actin network under mechanical stress. NMR structural analysis, in silico modeling, mutagenesis of interface residues, cell spreading assay, F-actin network mechanics PloS one High 19293932
2009 FilGAP is targeted to sites of force transfer by FLNa (specifically repeat 23). Force-induced redistribution of FilGAP is essential for suppression of Rac activity and lamellae formation in cells treated with tensile forces applied through integrins. Depletion of FilGAP by siRNA, inhibition by dominant-negative mutation, or deletion of its FLNa-binding domain all result in dramatic force-induced increase of annexin-V-positive (apoptotic) cells, establishing FilGAP as a mechanoprotective anti-apoptotic effector downstream of FLNa. siRNA knockdown, dominant-negative constructs, integrin-mediated force application, annexin-V staining for apoptosis, fluorescence microscopy Molecular biology of the cell Medium 19144823
2011 Mechanical strain in reconstituted actin/FLNa networks differentially regulates binding of FLNa partners: strain increases β-integrin binding to FLNa while causing FilGAP to dissociate from FLNa. Both externally imposed bulk shear and myosin-II-driven forces were shown to regulate this differential binding using fluorescence loss after photoconversion (FLAP). Reconstituted minimal system (actin filaments + FLNa + β-integrin tail + FilGAP), fluorescence loss after photoconversion (FLAP), bulk shear application, myosin-II inhibition Nature High 21926999
2011 Arhgap24 is upregulated in differentiating kidney podocytes and functions as a RhoA-activated Rac1-GAP in these cells. Arhgap24 knockdown increases active Rac1 and Cdc42 levels and alters podocyte cell shape and membrane dynamics. A disease-associated missense mutation in ARHGAP24 impairs its Rac1-GAP activity and co-segregates with familial focal segmental glomerulosclerosis (FSGS). siRNA knockdown in cultured podocytes, GTPase activation assays (active Rac1/Cdc42 pulldown), Sanger sequencing of FSGS patients, in vitro GAP activity assay of mutant protein The Journal of clinical investigation High 21911940
2012 FilGAP is a mediator of Rho/ROCK-dependent amoeboid movement of carcinoma cells. Depletion of FilGAP induces elongated mesenchymal morphology; forced expression induces round/amoeboid morphology requiring Rho/ROCK-dependent phosphorylation of FilGAP. Depletion of FilGAP impairs breast cancer cell invasion through ECM and reduces tumor cell extravasation in vivo. siRNA knockdown, forced expression, cell morphology analysis, Matrigel invasion assay, in vivo extravasation assay Molecular biology of the cell Medium 23097497
2014 FilGAP binds to activated Arf6 through its pleckstrin homology (PH) domain and is recruited to plasma membranes. Activated Arf6 stimulates the RacGAP activity of FilGAP. Knockdown of endogenous Arf6 by siRNA suppresses FilGAP-mediated bleb formation. A FilGAP mutant lacking PIP3 binding (R39C) still binds activated Arf6 and induces bleb formation, indicating a PIP3-independent interaction with Arf6.

2015 Phosphorylation of FilGAP serine 402 by ROCK regulates its subcellular localization: non-phosphorylatable FilGAP (S402A) localizes to actin cytoskeleton, while phosphomimetic or ROCK-phosphorylated FilGAP is diffusely cytoplasmic. Dephosphorylation of Ser-402 accompanies cell spreading on fibronectin. Calyculin A (Ser/Thr phosphatase inhibitor) suppresses spreading of WT FilGAP cells but not S402A cells. Arf6 activation stimulates bleb formation by both non-phosphorylatable and phosphomimetic FilGAP mutants.

2015 FilGAP promotes formation of adherens junctions in MDCK epithelial cells downstream of Rho-ROCK signaling. Knockdown of FilGAP stimulates HGF-induced disassembly and cell scattering; forced expression induces accumulation of E-cadherin at adherens junctions. The Rac GAP domain of FilGAP is required for suppression of HGF-induced scattering. ROCK-induced accumulation of E-cadherin at adherens junctions requires FilGAP and its ROCK-dependent phosphorylation (non-phosphorylatable FilGAP mutant fails to rescue). siRNA knockdown, forced expression, E-cadherin surface staining, HGF-induced scattering assay, ROCK overexpression, non-phosphorylatable mutant rescue Journal of cell science Medium 25908853
2016 RBM10 is a FilGAP-interacting protein. Src family tyrosine kinase Fyn induces translocation of RBM10 from nucleus to cell periphery in a kinase-activity-dependent manner, where RBM10 co-localizes with FilGAP. RBM10 is required for targeting FilGAP to the cell periphery during spreading, and association of RBM10 with FilGAP stimulates FilGAP's RacGAP activity as shown by suppression of spreading, ruffle formation, and FilGAP-dependent protrusive structures.

2017 ARHGAP24 is required for regulation of ARF6-dependent pseudopod formation in breast carcinoma cells. Knockdown of ARHGAP24 increases the lifespan and length of pseudopods induced by activated ARF6. ARHGAP24 requires its ARF6-binding site to achieve ARF6-dependent actin remodeling. siRNA knockdown of ARHGAP24, activated ARF6 expression, pseudopod measurement by time-lapse microscopy, binding-site mutant analysis Anticancer research Low 28870903
2019 AGAP1 (an Arf GAP) binds to the C-terminus of FilGAP through AGAP1's N-terminal GLD domain. FilGAP co-localizes with AGAP1 at intracellular vesicles, and FilGAP targeting to these vesicles requires its interaction with AGAP1. Depletion of AGAP1 causes accumulation of endogenous FilGAP at paxillin-positive focal adhesions and actin structures, suppresses cell spreading on collagen (relieved by co-depletion of FilGAP), and promotes cell invasion that is blocked by FilGAP depletion.

2019 FilGAP regulates distinct stages of MDCK epithelial tubulogenesis downstream of Rho-ROCK signaling. Depletion of FilGAP increases HGF-induced basolateral extensions from cysts; forced expression decreases extensions. Phosphomimetic FilGAP (ST/D) blocks membrane extension formation even in the presence of ROCK inhibitor Y-27632, and promotes lumen formation while blocking cell scattering in tubules. siRNA knockdown, forced expression, 3D MDCK cyst culture in ECM, HGF stimulation, ROCK inhibitor Y-27632, phosphomimetic mutant (ST/D) Biochemical and biophysical research communications Low 31078260
2021 FilGAP controls front-rear polarity and tumor cell migration speed through extracellular matrix. FilGAP localizes to the cell front through its PH domain in a PIP3-dependent manner to inactivate Rac at that site. Small GTPase Arf6 (binding to the FilGAP PH domain) also regulates FilGAP-mediated cell polarity and migration.

2022 ARHGAP24 acts as a GTPase-independent scaffold in hepatocellular carcinoma to suppress β-catenin signaling. It recruits the E3 ubiquitin ligase WWP1 to promote degradation of pyruvate kinase M2 (PKM2). The C-terminal fragment of ARHGAP24 (aa 329-430) binds WWP1 and aa 631-748 binds PKM2 (aa 388-531). A GAP-deficient ARHGAP24 mutant exerts the same inhibitory effects as wild-type, confirming GAP-independent scaffolding function.

2023 FilGAP interacts with mTORC1 via Raptor and with mTORC2 via Rictor and Sin1. Depletion of FilGAP decreases phosphorylation of S6K (mTORC1 substrate) and AKT (mTORC2 substrate) in KINGS-1 glioma cells; conversely, overexpression of FilGAP increases these phosphorylations, indicating FilGAP activates mTORC1/2. FilGAP depletion reduces spheroid growth.

2023 FilGAP localizes to invadopodia through its PH domain binding to phosphatidylinositol 3,4-bisphosphate [PI(3,4)P2] and negatively regulates invadopodia formation by inactivating Rac1. Depletion of FilGAP or expression of GAP-deficient FilGAP mutant increases invadopodia formation and ECM degradation; overexpression suppresses both. PI(3,4)P2 depletion reduces FilGAP invadopodia localization. siRNA knockdown, forced expression, GAP-deficient mutant, PH domain PI(3,4)P2-binding mutant, gelatin degradation assay, EGF stimulation, fluorescence localization Cell structure and function Medium 37482421
2024 FilGAP is phosphorylated at Ser625 by p90 ribosomal S6 kinase (RSK) downstream of EGF signaling, followed by phosphorylation at Ser621 by GSK3 in a sequential manner. This phosphorylation induces dissociation of FilGAP from actin filaments via a novel actin-localization domain. Phosphorylation inhibits FilGAP's lamellipodia-suppression activity. Non-phosphorylatable FilGAP mutant reduces cell migration speed and persistence toward EGF gradient, establishing this cascade as a regulator of chemotactic tumor cell migration.

2024 FilGAP controls cell-ECM adhesion and process formation in podocytes by suppressing Rac1/PAK1 signaling. FilGAP localizes to focal adhesions (FAs); its depletion decreases FA formation, impairs attachment to ECM, increases Rac1 activity, and reduces formation of major processes and foot process-like projections. These deficits are rescued by inhibition of Rac1 or PAK1, placing PAK1 as a downstream effector of FilGAP/Rac1 in podocyte morphology. siRNA knockdown, forced expression, Rac1 activity pulldown assay, focal adhesion staining (paxillin/vinculin), podocyte process formation assay, Rac1 inhibitor, PAK1 inhibitor rescue FASEB journal Medium 38421271
