Mechanistic narrative

Synthesis pass · prose summary of the discoveries below

AFAP1 (AFAP-110) is a multidomain adaptor and actin cross-linking protein that couples PKCα and PI3K signaling to c-Src activation and actin cytoskeletal remodeling, driving podosome formation, focal adhesion regulation, and cell migration (PMID:15314167, PMID:17360811). Its amino terminus carries SH3- and SH2-binding modules that engage activated Src: an SH3-binding motif mediates stable complex formation and efficient tyrosine phosphorylation, while two independently functional SH2-binding regions (Y94 and Y451/Y453) cooperate in a multistep binding mechanism (PMID:9350057, PMID:9655255). The carboxy-terminal actin-binding domain is necessary and sufficient for direct, cooperative actin filament binding and cross-linking, and is required for cytoskeletal localization (PMID:10666339, PMID:12134071, PMID:21984596). These activities are held under intramolecular auto-inhibition by a carboxy-terminal leucine zipper that contacts the PH1 domain and constrains multimerization; structural disruption of the zipper, or activated-Src-induced conformational change, relieves this inhibition and separates the distinct outputs of actin cross-linking versus Src activation (PMID:9619827, PMID:14755689). Upstream, PKCα phosphorylates AFAP1 at Ser277 to regulate podosome stability and turnover, PI3K activity and the PH1 domain enable AFAP1–c-Src colocalization, and Rho acts downstream in the actin reorganization arm (PMID:11641786, PMID:17360811, PMID:18577577). AFAP1 is required for stress fiber and focal adhesion formation, integrin β1-dependent adhesion, and tumorigenic growth of prostate and breast cancer cells (PMID:17520695, PMID:17885682), and it is recruited to podosomes by the Tks5 fifth SH3 domain (PMID:19540230). Independently, AFAP1 is a phosphorylation-dependent, non-transcriptional mediator of TNF-α–induced attenuation of P-glycoprotein efflux at the blood-brain barrier (PMID:28112407).

2004 AFAP-110 (AFAP1) is required to mediate PKCα activation of c-Src and subsequent podosome formation. PKCα activation directs AFAP-110 to colocalize with and bind the c-Src SH3 domain, activating the tyrosine kinase. In cells lacking AFAP-110 (CaOV3), PMA could not activate c-Src or induce podosomes; ectopic AFAP-110 rescued these effects. AFAP-110 mutants unable to bind or colocalize with c-Src failed to rescue. Immunofluorescence, ectopic expression of constitutively active PKCα, rescue experiments with AFAP-110 mutants in AFAP-110-deficient CaOV3 cells Molecular and cellular biology High 15314167
2001 AFAP-110 functions as an adaptor protein linking Src family kinases to actin filaments via: (1) SH3/SH2 binding modules in its amino terminus, (2) two pleckstrin homology domains, (3) a leucine zipper motif mediating self-association, (4) a carboxy-terminal actin-binding domain enabling direct actin filament interaction. Conformational changes associated with phosphorylation or mutagenesis reveal an intrinsic capability to alter actin filament integrity and activate cSrc.

1997 The amino-terminal SH3 binding motif I (SH3bm I) of AFAP-110 is required for stable complex formation with Src and for efficient tyrosine phosphorylation by Src. A proline-to-alanine mutation in SH3bm I abolished GST-SH3 absorption and reduced tyrosine phosphorylation ~2.7-fold, and prevented stable complex formation with activated Src (pp60-527F). Site-directed mutagenesis of SH3 binding motif, GST-SH3 pulldown, co-expression of Src527F with AFAP-110 mutants in Cos-1 cells, co-immunoprecipitation Molecular and cellular biochemistry High 9350057
1998 The carboxy-terminal 127 amino acids of AFAP-110 contain an alpha-helical leucine zipper motif required for self-association (multimerization). Activated Src (Src527F) disrupts carboxy-terminal interactions, shifting AFAP-110 to a multimeric population. Deletion of the leucine zipper region repositions actin filaments into rosette-like structures similar to Src-transformed cells and promotes lamellipodia-like structures. The carboxy terminus is required for colocalization with actin filaments and the cell membrane. GST fusion protein affinity absorption, Superose size-exclusion chromatography, deletional mutagenesis, immunofluorescence in cells co-expressing Src527F Oncogene High 9619827
2000 The carboxy terminus of AFAP-110 is both necessary and sufficient for direct actin filament association in vivo and in vitro. The carboxy-terminal actin-binding domain shows ~40% similarity to known actin-binding motifs. Deletion of the leucine zipper motif (AFAP-Δlzip) enables AFAP-110 to alter actin filament integrity and induce lamellipodia formation in untransformed cells. The leucine zipper motif normally constrains these activities. In vitro actin filament binding assay with recombinant carboxy-terminal domain, deletional mutagenesis, cellular expression with immunofluorescence in untransformed fibroblasts Experimental cell research High 10666339
2001 AFAP-110(Δlzip), a leucine zipper deletion mutant, activates cellular tyrosine kinases including Src family members and becomes hyperphosphorylated on tyrosine. This activation requires integrity of the SH3-binding motif of AFAP-110(Δlzip). A deletion within the PH domain also reverts the effects on actin filaments. Dominant-positive RhoA(V14) blocks AFAP-110(Δlzip)-induced actin filament rosettes but not Src activation, placing Rho downstream of AFAP-110-directed Src activation in the actin reorganization pathway. Expression of deletion and point mutants, immunofluorescence, kinase activity assays, co-expression with dominant-active RhoA Oncogene High 11641786
2002 Recombinant AFAP-110 binds actin filaments cooperatively through lateral association and can cross-link actin filaments in a manner dependent on the carboxy-terminal actin-binding domain. Deletion of the leucine zipper or PKC phosphorylation alters AFAP-110 conformation, reduces multimerization stability, and increases its capacity to cross-link actin filaments. PKC activation in cells causes loss of stress fibers, formation of motility structures, and strong AFAP-110 colocalization with these structures. Expression of an AFAP-110 mutant unable to bind PKC blocked PMA effects on actin filaments.

1998 AFAP-110 forms a stable complex with activated Src through either of two independently functional SH2-binding motifs: one in the amino terminus (Y94) and one in the carboxy terminus (Y451 and Y453). Mutation of Y93/Y94 or Y451/Y453 alone does not fully abrogate complex formation, but triple-tyrosine mutations (combining both regions) drastically reduce phosphorylation and prevent stable complex formation. A multistep SH2/SH3 binding mechanism is supported.

2004 The leucine zipper motif of AFAP-110 regulates actin filament cross-linking and Src activation through both sequence and structural requirements. The leucine zipper facilitates intramolecular auto-inhibition by contacting the amino-terminal PH1 domain. Disruption of multimer stability (by Δlzip, fos-Lzip substitution, or L581P helix mutation) increases in vitro actin cross-linking; however, only structural disruptions (Δlzip, L581P) activate cSrc and alter actin integrity in vivo, indicating that actin cross-linking and Src activation are distinct functions.

2007 AFAP-110 (AFAP1) is required for actin stress fiber formation and cell adhesion to fibronectin in MDA-MB-231 breast cancer cells. Knockdown of AFAP-110 abolishes stress fiber cross-linking and focal adhesion formation without affecting proliferation or expression of focal adhesion components. LPA treatment cannot rescue stress fiber and focal adhesion formation in AFAP-110 knockdown cells. siRNA knockdown, inducible knockdown, immunofluorescence, fibronectin adhesion assay, LPA stimulation Journal of cellular physiology High 17520695
2007 AFAP-110 (AFAP1) is required for tumorigenic growth of prostate cancer cells, regulating focal contacts in a PKC-dependent manner. Downregulation of AFAP-110 reduced cell-matrix adhesion, migration, defective focal adhesions, and reduced integrin β1 expression. Reintroduction of avian AFAP-110 or a Src-interaction-disabled mutant restored these properties, but an AFAP-110 lacking the PKC-interacting domain failed to restore them, demonstrating PKC-dependent regulation of focal contacts.

2007 PI3K activation is required for PMA/PKCα-induced colocalization of AFAP-110 with c-Src and subsequent c-Src activation. The amino-terminal PH1 domain of AFAP-110 is required for colocalization with c-Src, while the SH3-binding motif is required for activation. PI3K inhibitors and cells lacking p85α/β PI3K regulatory subunits block AFAP-110–c-Src colocalization and activation. This pathway promotes cell migration.

Cell physiology High 17360811
2008 PKCα phosphorylates AFAP-110 at Ser277 in response to phorbol ester treatment, and phospho-Ser277 AFAP-110 localizes to podosomes. Mutation of Ser277 to Ala (AFAP-110-S277A) does not alter podosome localization but increases podosome number and lifespan (demonstrated by video microscopy), indicating that Ser277 phosphorylation regulates podosome stability and turnover.

2009 Tks5 recruits AFAP-110, p190RhoGAP, and cortactin to podosomes via its fifth SH3 domain. Mislocalization of Tks5 to mitochondria causes redistribution of AFAP-110, p190RhoGAP, and cortactin to perinuclear regions and inhibits podosome formation. A Tks5 mutant lacking the PX domain also inhibits podosome formation and redistributes AFAP-110.

1995 An alternatively spliced brain-specific variant of AFAP-110, designated AFAP-120, contains an additional 258 bp open reading frame encoding a novel internal sequence (NINS) with a proline-rich SH3-binding motif. The NINS-GST fusion protein pulls down a 67-kDa protein from tissue lysates; deletion analysis maps this interaction to the proline-rich motif. cDNA cloning, northern blot, western blot, GST-NINS pulldown assay with deletion mutants, transient expression The Journal of biological chemistry Medium 7876134
2011 Endogenous AFAP1 localizes to both cytoskeletal and cytosolic fractions; depolymerization of actin filaments (cytochalasin D or latrunculin A) increases AFAP1 in the cytosolic fraction, demonstrating actin-dependent localization. An AFAP1 mutant lacking the actin-binding domain (AFAPΔABD) localizes predominantly to the cytosolic fraction, is associated with disorganized cytoskeleton, reduced stress fibers, and accumulation of F-actin at the membrane and podosome-like structures that co-localize with cortactin but do not digest gelatin, and show reduced interaction with c-Src.

2011 AFAP1L1, a paralog of AFAP1 in the AFAP family, preferentially interacts with the SH3 domain of cortactin (not c-Src), in contrast to AFAP1 which binds cSrc SH3 but not cortactin. Overexpression of AFAP1L1 in A7r5 cells induces podosome formation without stimulation and colocalizes with cortactin at invadosomes.

2017 AFAP1 (the protein) is a key mediator of TNF-α-induced rapid attenuation of P-glycoprotein (P-gp) efflux activity at the blood-brain barrier. TNF-α rapidly decreases P-gp efflux activity without changing P-gp protein expression. Phosphoproteomics identified AFAP1 as significantly phosphorylated upon TNF-α treatment. Knockdown of AFAP1 blocked the TNF-α-induced reduction in P-gp efflux activity, while MAPK1 inhibition or AP-1 knockdown did not, demonstrating a specific non-transcriptional role for AFAP1 in inflammatory modulation of P-gp function.
