|Other Names||Histone H2B type 2-F, HIST2H2BF|
|Target/Specificity||A synthetic peptide corresponding to residues of human Histone H2B was used as an immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Histone H2B Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling.|
|Cellular Location||Nucleus. Chromosome.|

Changes in chromatin structure play a key role in the regulation of transcription in eukaryotes (1). The nucleosome is the primary building block of chromatin, and is made up of four core histone proteins (H2A, H2B, H3 and H4) (2). Acetylation of core histones regulates gene expression (2). Histone H2B is acetylated in the N-terminal region, primary at lysines 5, 12, 15, and 20 (3). Ubiquitylation of histone H2B at lysine 123 by Rad6 has been implicated in transcriptional activation and lysine methylation on histone H3 (4). Histone H2B phosphorylation at Ser10 (for yeast) and Ser14 (for mammalian cells) has been linked to regulation of cell apoptosis and meiosis (5).
