A number of ELISA Kits are available that target adaptor-related protein complex AP-4, mu 1, an alias of the protein, adaptor related protein complex 4 subunit mu 1. The human protein, encoded by the gene AP4M1, is a member of the Adaptor complexes medium subunit family. Additional synonyms or past names for this protein may include: CPSQ3|MU-4|MU-ARP2|SPG50. Homology is conserved in other species, such as Mouse, Rat, Zebrafish, Frog, Chicken.
