General annotation (Comments)

Function

Assembly protein recruiting clathrin and adaptor protein complex 2 (AP2) to cell membranes at sites of coated-pit formation and clathrin-vesicle assembly. May be required to determine the amount of membrane to be recycled, possibly by regulating the size of the clathrin cage. Involved in AP2-dependent clathrin-mediated endocytosis at the neuromuscular junction By similarity. UniProtKB Q13492

Subunit structure

Binds clathrin and phosphatidylinositol 4,5-bisphosphate.

Subcellular location

Membraneclathrin-coated pit By similarity. Golgi apparatus By similarity. Cytoplasmic vesicleclathrin-coated vesicle By similarity. Note: Colocalized with clathrin in the Golgi area By similarity.

Tissue specificity

Isoform 2 was found in most tissues examined. Isoform 1 has an overlapping expression pattern but is absent from lung, heart and pancreas. Both isoforms are widely expressed in the brain, higher levels are seen in hippocampus, dentate gyrus, medial habenula nucleus and cerebellar granule cells. Ref.1

Sequence similarities

Contains 1 ENTH (epsin N-terminal homology) domain.
