Target Background

Function
Histone H3 is a core component of nucleosomes. Nucleosomes wrap and compact DNA into chromatin, restricting DNA accessibility to cellular machineries that utilize DNA as a template. Thus, histones play a pivotal role in regulating transcription, DNA repair, DNA replication, and chromosomal stability. The accessibility of DNA is regulated through a complex system of post-translational modifications of histones, often referred to as the histone code, and nucleosome remodeling.
