靶标

  • 功能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.
  • 序列相似性Belongs to the histone H2B family.
  • 翻译后修饰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.
    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.
    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.
    Sumoylation to form H2BK6su or H2BK7su, and probably also H2BK16su or H2BK17su, occurs preferentially near the telomeres and represses gene transcription.
