Protein Information (annotations from UniProt)

Database IDHIV0001240
UniProt IDQ71UI9
Primary gene name(s)H2AFV
Synonym gene name(s)H2AV
Protein nameHistone H2A.V
Protein functionVariant histone H2A which replaces conventional H2A in a subset of nucleosomes. 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. May be involved in the formation of constitutive heterochromatin. May be required for chromosome segregation during cell division, By similarity. {ECO:0000250}.
