The Variant [https://www.uniprot.org/uniprot/P84243 histone H3] replaces H3 in a range of nucleosomes in active genes. Deposited at sites of nucleosomal displacement throughout transcribed genes, suggesting that it represents an epigenetic imprint of transcriptionally active chromatin. 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 | The Variant [https://www.uniprot.org/uniprot/P84243 histone H3] replaces H3 in a range of nucleosomes in active genes.
