Histone H2B (UniProt: Q8N257; also known as H2B, H2B type 12) is encoded by the HIST3H2BB gene (Gene ID: 128312) in human. Histones are basic nuclear proteins that are responsible for the nucleosome structure of chromatin in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which DNA is wrapped in repeating units, called nucleosomes, which limits DNA accessibility to the cellular machineries, which require DNA as a template. Histones 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. Histone H2B is one of the main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N terminal tail, H2B is involved with the structure of the nucleosomes of the ′beads on a string′ structure. Histone H2B can be monoubiquitinated on Lysine 35 by the MSL1/MSL2 dimer and this ubiquitination is reported to be essential for histone H3 lysine 4 (H3K4me) and lysine 79 (H3K79me) methylation and transcription activation at specific gene loci, such as HOXA9 and MEIS1 loci. Similarly, monoubiquitination at lysine 121(H2BK120Ub) by the RNF20/40 complex gives a specific tag for epigenetic transcriptional activation and is a prerequisite for histone H3 lysine 4 and lysine 79 methylation. Histone H2B undergoes phosphorylation at serine 37 by AMPK in response to stress and promotes transcription. During apoptosis and DNA double strand breaks it is phosphorylated on serine 15 by STK4/MST1 that facilitates apoptotic chromatin condensation. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.
