Deposited at sites of nucleosomal displacement throughout transcribed genes which represents an epigenetic imprint of active chromatin. Nucleosomes wrap and compact DNA into chromatin. Also Histones 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 Structural highlights in a PubMed abstract,CENP-Awhich is a centromere-specific histone H3 variant is over expressed in cancer cells and it can be mislocalized ectopically in the form of heterotypic nucleosomes containing H3.3.
