Anti-H2A clustered histone 7 antibodies are used for the immunodetection of the protein encoded by the H2AC7 gene. In humans, the canonical protein has a reported length of 130 amino acid residues and a mass of 14.1 kDa. Its subcellular localization is in the nucleus and chromosomes. A member of the Histone H2A protein family, it is an important component of nucleosome. Post-translational modifications have been described, including ubiquitination, acetylation and phosphorylation. Other names for this target antigen include H2A/g, H2AFG, HIST1H2AD, histone H2A type 1-D, H2A histone family, member G, and H2A.3. Gene orthologs have been identified in the mouse and rat species.
