Anti-BRD2 antibodies are used in the immunodetection of the protein bromodomain containing 2. In humans, the canonical protein has a reported length of 801 amino acid residues and a mass of 88.1 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 4 different isoforms for this protein. BRD2 is believed to play a role in spermatogenesis or folliculogenesis (By similarity). Synonyms for this target antigen include D6S113E, FSH, FSHRG1, FSRG1, NAT, O27.1.1, RING3, and BRD2-IT1.
