gH2A

Gene
gH2A
Protein
Histone H2A.2
Organism
Lilium longiflorum
Length
128 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. May be involved in the repression of gene expression in male gametes.
Similarity
Belongs to the histone H2A family.
