H2B-1

Gene
H2B-1
Protein
Histone H2B.1
Organism
Solanum lycopersicum
Length
142 amino acids
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.
Similarity
Belongs to the histone H2B family.
