Anti-ABCA2 antibodies are used in the immunodetection of the protein ATP binding cassette subfamily A member 2. In humans, the canonical protein has a reported length of 2435 amino acid residues and a mass of 269.8 kDa. Its subcellular localization is in the endosome and lysosomes. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the ABCA protein family, ABCA2 is a suspected lipid transporter that modulates cholesterol sequestration in the late endosome/lysosome by regulating the intracellular sphingolipid metabolism, in turn participates in cholesterol homeostasis. Synonyms for this target antigen include IDPOGSA, ATP-binding cassette 2, ATP-binding cassette transporter 2, ATP-binding cassette, sub-family A (ABC1), member 2, and ABC2. ABCA2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some ABCA2 antibodies may have been used in research and have associated citations. Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
