Anti-BEX2 antibodies are used in the immunodetection of the protein brain expressed X-linked 2. In humans, the canonical protein has a reported length of 128 amino acid residues and a mass of 15.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in central nervous system, with high level in pituitary, cerebellum and temporal lobe. A member of the BEX protein family, BEX2 is a reported regulator of mitochondrial apoptosis and G1 cell cycle in breast cancer. Synonyms for this target antigen include brain-expressed X-linked protein 2, hBex2, and protein BEX2. BEX2 gene orthologs have been reported in the mouse, rat and chimpanzee species. Some BEX2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
