Anti-AP1B1 antibodies are used in the immunodetection of the protein adaptor related protein complex 1 subunit beta 1. In humans, the canonical protein has a reported length of 949 amino acid residues and a mass of 104.6 kDa. Its subcellular localization is in the cytoplasmic vesicles, Golgi, and membrane. Up to 4 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the Adaptor complexes large subunit protein family, AP1B1 is known to be involved with cardiac tissue development and intracellular protein transport. Synonyms for this target antigen include AP105A, BAM22, CLAPB2, KIDAR, AP-1 complex subunit beta-1, and ADTB1. AP1B1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of AP1B1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
