Anti-H2B clustered histone 15 antibodies are used for the immunodetection of the protein encoded by the H2BC15 gene. In humans, the canonical protein has a reported length of 126 amino acid residues and a mass of 13.9 kDa. Its subcellular localization is in the nucleus and chromosomes. A member of the Histone H2B protein family, it is an important component of nucleosome. Post-translational modifications have been described, including glycosylation, ubiquitination and phosphorylation. Other names for this target antigen include H2BFD, HIST1H2BN, histone H2B type 1-N, H2B histone family, member D, histone 1, H2bn, and H2B/d.
