General annotation (Comments)
| Function | Can cross-link actin filaments into both network and bundle structures By similarity. May modulate changes in actin filament integrity and induce lamellipodia formation. May function as an adapter molecule that links other proteins, such as SRC and PKC to the actin cytoskeleton. Seems to play a role in the development and progression of prostate adenocarcinoma by regulating cell-matrix adhesions and migration in the cancer cells. Ref.1 Ref.8 |
| Subunit structure | Monomer and homomultimer. Interacts via its C-terminus with F-actin; probably involving AFAP1 multimers By similarity. Interacts with activated SRC SH3-SH2 domains. Interacts via its PH 1 domain with PRKCA, PRKCB and PRKCI By similarity. Ref.1 |
| Subcellular location | Cytoplasm › cytoskeleton. Note: Localizes with stress fibers in quiescent cells, concentrated in cell motility structures such as lamellipodia, filopodia and membrane ruffles upon their induction. Ref.1 |
| Tissue specificity | Low expression in normal breast epithelial cell line MCF-10A and in tumorigenic breast cancer cell lines MCF-7, T-47D and ZR-75-1. Highly expressed in the invasive breast cancer cell lines MDA-MB-231 and MDA-MB-435. Overexpressed in prostate carcinoma. Ref.7 Ref.8 |
| Post-translational modification | Phosphorylated on tyrosine residues by SRC. Ref.1 |
| Miscellaneous | Knockdown in MDA-MB-231 cells resulted in loss of actin stress fibers, decreased adhesion and spreading on fibronectin. |
| Sequence similarities | Contains 2 PH domains. |
