Anti-adaptor-related protein complex 3, mu 1 subunit antibodies enable researchers to detect and measure the adaptor-related protein complex 3, mu 1 subunit antigen in biological samples. This target is a reported synonym of the AP3M1 gene, which encodes adaptor related protein complex 3 subunit mu 1. This protein is known to function in endocytosis and vesicle-mediated transport, among other biological roles. The human version of adaptor-related protein complex 3, mu 1 subunit has a canonical amino acid length of 418 residues and a protein mass of 46.9 kilodaltons. It is reported to be localized in the cytoplasmic vesicles, Golgi, and membrane of cells. Other names for this target antigen include AP-3 complex subunit mu-1, AP-3 adapter complex mu3A subunit, and adapter-related protein complex 3 mu-1 subunit.
