Anti-BAIAP3 antibodies are used in the immunodetection of the protein BAI1 associated protein 3. In humans, the canonical protein has a reported length of 1187 amino acid residues and a mass of 131.9 kDa. Its subcellular localization is in the cell membrane, Golgi, and cytoplasm. Up to 6 different isoforms have been reported for this protein. It is reported to be highly expressed in the brain. A member of the Unc-13 protein family, BAIAP3 is reported to function in endosome to Golgi retrograde transport. Synonyms for this target antigen include BAI-associated protein 3, brain-specific angiogenesis inhibitor I-associated protein 3, and BAP3. BAIAP3 gene orthologs have been reported in the mouse, rat, frog, zebrafish and chimpanzee species. Some BAIAP3 antibodies may have been used in research and have associated citations. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
