Gene:
adaptor-related protein complex 4, epsilon 1 subunit
Description:
The heterotetrameric adaptor protein (AP) complexes sort integral membrane proteins at various stages of the endocytic and secretory pathways. AP4 is composed of 2 large chains, beta-4 (AP4B1; MIM 607245) and epsilon-4 (AP4E1), a medium chain, mu-4 (AP4M1; MIM 602296), and a small chain, sigma-4 (AP4S1; MIM 607243).[supplied by OMIM]
