General annotation (Comments)
| Function | Plays a role in the formation of normal, flask-shaped caveolae at the cell membrane. Recruits DNM2 to caveolae, and thereby plays a role in caveola-mediated endocytosis. Plays a role in intracellular vesicle-mediated transport. Binds to membranes via its F-BAR domain and promotes membrane tubulation. Plays a role in the internalization of cell-surface receptors. Is not required for internalization of EGFR after EGF stimulus, but contributes to the internalization of EGFR in the absence of EGF stimulus. Ref.12 Ref.13 Ref.15 Ref.16 |
| Subunit structure | Homodimer. May form heterooligomers with other PACSINs. Interacts (via SH3 domain) with DNM1, SYN1, SYNJ1 and WASL. Interacts with EHD1 and EHD3. Interacts with CAV1 By similarity. Interacts with RAC1. Ref.13 |
| Subcellular location | Cytoplasm By similarity. Cytoplasm › cytoskeleton By similarity. Cytoplasmic vesicle membrane; Peripheral membrane protein; Cytoplasmic side. Early endosome. Cell projection › ruffle membrane; Peripheral membrane protein; Cytoplasmic side. Cell membrane; Peripheral membrane protein; Cytoplasmic side. Cell projection By similarity. Membrane › caveola. Note: Detected at the neck of flask-shaped caveolae. Ref.12 Ref.13 Ref.15 |
| Tissue specificity | |
| Domain | The F-BAR domain forms a coiled coil and mediates membrane-binding and membrane tubulation. In the autoinhibited conformation, interaction with the SH3 domain inhibits membrane tubulation mediated by the F-BAR domain. Ref.12 Ref.16 Ref.17 Ref.18 |
| Post-translational modification | Phosphorylated by casein kinase 2 (CK2) and protein kinase C (PKC) By similarity. |
| Sequence similarities | Belongs to the PACSIN family. Contains 1 FCH domain. Contains 1 SH3 domain. |
