Background of the antigen
AAK1 phosphorylates the AP2M1/mu2 subunit of the adaptor protein complex 2 (AP-2). It may play a role in regulating aspects of clathrin-mediated endocytosis. [SUBCELLULAR LOCATION] Membrane; Peripheral membrane protein (By similarity). Cell membrane; Peripheral membrane protein (By similarity). Membrane, clathrin-coated pit (By similarity). Note=Active when found in clathrin-coated pits at the plasma membrane (By similarity).
