H2Bv3

Gene
H2Bv3
Protein
Histone H2B.v3
Organism
Dictyostelium discoideum
Length
154 amino acids
Function
Core component of nucleosome which plays a central role in DNA double strand break (DSB) repair. 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 (By similarity).
Similarity
Belongs to the histone H2B family.
