Secondary Accession Numbers
  • 13438
Name Histone H2A type 2-A
Synonyms
  1. Histone H2A.2
  2. Histone H2A/o
Gene Name HIST2H2AA3
Protein Type Unknown
Biological Properties
General Function Involved in DNA binding
Specific 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
