Target Background

Function
Histone H3 is a core component of the nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to cellular machinery that requires DNA as a template. Thus, histones play a crucial role in transcription regulation, DNA repair, DNA replication, and chromosomal stability. DNA accessibility is regulated through a complex set of post-translational modifications of histones, also known as the histone code, and nucleosome remodeling.
