| Host | Rabbit |
| Specificity | Reacts with histone H2B in human nuclear fractions. No cross-reactivity with other histones, H1, H2A, H3 or H4. Binding of histones from other species has not been tested, but it is likely as the amino acid sequence of histone H2B has been found to be identical in all species examined. |

| Entrez Gene Number |
|
| Entrez Gene Summary | Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene is intronless and encodes a member of the histone H2B family. Transcripts from this gene contain a palindromic termination element. |

| UniProt Summary | FUNCTION: SwissProt: Q8N257 # 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. SIZE: 126 amino acids; 13908 Da SUBUNIT: The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of DNA. SUBCELLULAR LOCATION: Nucleus. PTM: Monoubiquitination of Lys-121 by the RNF20/40 complex gives a specific tag for epigenetic transcriptional activation and is also prerequisite for histone H3 Lys-4 and Lys-79 methylation. It also functions cooperatively with the FACT dimer to stimulate elongation by RNA polymerase II. & Phosphorylated on Ser-15 by STK4/MST1 during apoptosis; which facilitates apoptotic chromatin condensation. Also phosphorylated on Ser-15 in response to DNA double strand breaks (DSBs), and in correlation with somatic hypermutation and immunoglobulin class- switch recombination. SIMILARITY: SwissProt: Q8N257 ## Belongs to the histone H2B family. |
