General annotation (Comments)
| Function | Required to coordinate membrane tubulation with reorganization of the actin cytoskeleton during endocytosis. May bind to lipids such as phosphatidylinositol 4,5-bisphosphate and phosphatidylserine and promote membrane invagination and the formation of tubules. Also promotes CDC42-induced actin polymerization by activating the WASL/N-WASP-WASPIP/WIP complex, the predominant form of WASL/N-WASP in cells. Actin polymerization may promote the fission of membrane tubules to form endocytic vesicles. Essential for autophagy of intracellular bacterial pathogens. Ref.1 Ref.5 Ref.10 |
| Subunit structure | Homodimerizes, the dimers can polymerize end-to-end to form filamentous structures By similarity. Interacts with GTP-bound CDC42. Interacts with DAAM1, DIAPH1, DIAPH2, DNM1, DNM2 and WASL/N-WASP. Interacts with ATG3. Ref.1 Ref.5 Ref.6 Ref.7 Ref.10 |
| Subcellular location | Cytoplasm. Cytoplasm › cytoskeleton By similarity. Cytoplasm › cell cortex By similarity. Cytoplasmic vesicle By similarity. Cell membrane; Peripheral membrane protein; Cytoplasmic side By similarity Ref.8. |
| Domain | The F-BAR domain binds the phospholipid membrane with its concave surface. The end-to-end polymerization of dimers of these domains provides a curved surface that fits best membranes with around 600 A diameter, and may drive tubulation By similarity. |
| Sequence similarities | Belongs to the FNBP1 family. Contains 1 FCH domain. Contains 1 REM (Hr1) repeat. Contains 1 SH3 domain. |
| Sequence caution | The sequence BAA91051.1 differs from that shown. Reason: Erroneous initiation. The sequence CAI18954.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI18981.1 differs from that shown. Reason: Erroneous gene model prediction. |
