Function
- role in endocytosis (putative)
- interacts with AP1G1 & AP2A1 components of the adapter protein complexes AP-1 & AP-2
- interacts with the GAE domain proteins GGA1, GGA2 & GGA3 (putative)
Structure
- belongs to the NECAP family
- WXXF motifs mediate binding of accessory proteins to the ear-domain of AP-1, GGAs & AP-2 through hydrophobic interactions. Selective binding to the GAE domains of AP-1 or to the alpha-ear domain of AP-2 is tuned by the acidic context surrounding the motif & the properties of the 2nd residue of the motif itself (putative)
Compartment
- cytoplasmic vesicle
- clathrin-coated vesicle membrane (putative)
- cell membrane
- colocalizes with AP-2 at the plasma membrane (putative)
Alternative splicing
named isoforms=3
