Enzyme Function |
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. {ECO:0000269|PubMed:12152067, ECO:0000269|PubMed:14752010, ECO:0000269|PubMed:15280549, ECO:0000269|PubMed:15632065, ECO:0000269|PubMed:15652479, ECO:0000269|PubMed:15970663, ECO:0000269|PubMed:16598039}. |

Post Translational Modification |
PTM: Monoubiquitinated by the RAD6/UBC2-BRE1 complex to form H2BK123ub1. H2BK123ub1 gives a specific tag for epigenetic transcriptional activation and is also prerequisite for H3K4me and H3K79me formation. H2BK123ub1 also modulates the formation of double-strand breaks during meiosis and is a prerequisite for DNA-damage checkpoint activation. Deubiquitination is performed by UBP8 in presence of SGF11.; PTM: Phosphorylated by STE20 to form H2BS10ph during progression through meiotic prophase. May be correlated with chromosome condensation. H2BS10ph is also formed after H(2)O(2) treatment, and is a step leading to apoptosis. {ECO:0000269|PubMed:15652479, ECO:0000269|PubMed:15970663}.; PTM: Acetylated by GCN5, a component of the SAGA complex, to form H2BK11ac and H2BK16ac. H2BK16ac can also be formed by ESA1, a component of the NuA4 histone acetyltransferase (HAT) complex. Acetylation of N-terminal lysines and particularly formation of H2BK11acK16ac has a positive effect on transcription. {ECO:0000269|PubMed:10777603, ECO:0000269|PubMed:11545749, ECO:0000269|PubMed:15186774, ECO:0000269|PubMed:16598039}.; PTM: Sumoylation to form H2BK6su or H2BK7su, and probably also H2BK16su or H2BK17su, occurs preferentially near the telomeres and represses gene transcription. {ECO:0000269|PubMed:15166219, ECO:0000269|PubMed:16598039}. |
