AP4M1
Chr 7ARadaptor related protein complex 4 subunit mu 1
Also known as: CPSQ3, MU-4, MU-ARP2, SPG50
This gene encodes a subunit of the heterotetrameric AP-4 complex. The encoded protein belongs to the adaptor complexes medium subunits family. This AP-4 complex is involved in the recognition and sorting of cargo proteins with tyrosine-based motifs from the trans-golgi network to the endosomal-lysosomal system.
