Anti-AP2A2 antibodies are used in the immunodetection of the protein adaptor related protein complex 2 subunit alpha 2. In humans, the canonical protein has a reported length of 939 amino acid residues and a mass of 104 kDa. Its subcellular localization is in the cell membrane. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in the brain. A member of the Adaptor complexes large subunit protein family, AP2A2 is a known component of the adaptor protein complex 2 (AP-2). Synonyms for this target antigen include CLAPA2, HIP-9, HIP9, HYPJ, AP-2 complex subunit alpha-2, and ADTAB. AP2A2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of AP2A2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
