General annotation (Comments)
| Function | Functions in an early step of clathrin-mediated endocytosis. Has both a membrane binding/bending activity and the ability to recruit proteins essential to the formation of functional clathrin-coated pits. Has a lipid-binding activity with a preference for membranes enriched in phosphatidylserine and phosphoinositides (Pi(4,5) biphosphate) like the plasma membrane. Its membrane-bending activity might be important for the subsequent action of clathrin and adaptors in the formation of clathrin-coated vesicles. Involved in adaptor protein complex AP-2-dependent endocytosis of the transferin receptor, it also functions in the AP-2-independent endocytosis of the LDL receptor. Ref.9 Ref.11 Ref.13 Ref.15 |
| Subunit structure | Homodimer; disulfide-linked. May form homotetramer. Interacts with AP2A1. Interacts with EPS15, EPS15R, ITSN1 and ITSN2; recruit those scaffolding proteins which in turn may interact with the adaptor protein complex AP-2 at the plasma membrane. Interacts with DAB2 (via DPF motifs); mediates LDL receptor/LDLR endocytosis. Ref.9 Ref.11 Ref.13 Ref.14 Ref.15 |
| Subcellular location | Membrane › clathrin-coated pit; Peripheral membrane protein; Cytoplasmic side By similarity. Note: Associated with forming but not mature clathrin-coated vesicles. The recruitment to coated-pits precede the one of clathrin and the adaptor protein complex AP-2 By similarity. Ref.11 Ref.13 |
| Post-translational modification | Ubiquitinated. Mainly undergoes monoubiquitination but also polyubiquitination By similarity. |
| Miscellaneous | Deforms liposomes into a range of tubule diameters from 20 to 130 nm in vitro. |
| Sequence similarities | Belongs to the FCHO family. Contains 1 FCH domain. Contains 1 MUHD (Muniscin C-terminal mu homology domain) domain. |
| Sequence caution | The sequence AAH14311.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
