AP2A1
This gene encodes the alpha 1 adaptin subunit of the adaptor protein 2 (AP-2) complex found in clathrin coated vesicles. The AP-2 complex is a heterotetramer consisting of two large adaptins (alpha or beta), a medium adaptin (mu), and a small adaptin (sigma). The complex is part of the protein coat on the cytoplasmic face of coated vesicles which links clathrin to receptors in vesicles. Alternative splicing of this gene results in two transcript variants encoding two different isoforms. A third transcript variant has been described, but its full length nature has not been determined.

Interaction
Adaptor protein complex 2 (AP-2) is a heterotetramer composed of two large adaptins (alpha-type subunit AP2A1 or AP2A2 and beta-type subunit AP2B1), a medium adaptin (mu-type subunit AP2M1) and a small adaptin (sigma-type subunit AP2S1). Interacts with SGIP1 (By similarity). Interacts with HIP1 and RAB11FIP2 (PubMed:11532990, PubMed:12364336). Interacts with SLC12A5 (By similarity). Interacts with clathrin (By similarity). Interacts with RFTN1 (PubMed:27022195). Interacts with KIAA1107 (PubMed:29262337). Interacts with PICALM (PubMed:16262731). Together with AP2B1 and AP2M1, it interacts with ADAM10; this interaction facilitates ADAM10 endocytosis from the plasma membrane during long-term potentiation in hippocampal neurons (PubMed:23676497). Interacts with ABCB11; this interaction regulates cell membrane expression of ABCB11 through its internalization in a clathrin-dependent manner and its subsequent degradation (PubMed:22262466).
