General annotation (Comments)

Function

Variant histone H3 which replaces conventional H3 in a wide range of nucleosomes in active genes. Constitutes the predominant form of histone H3 in non-dividing cells and is incorporated into chromatin independently of DNA synthesis. 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. Ref.2

Subunit structure

The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of DNA.

Subcellular location

Nucleus By similarity. Chromosome By similarity.

Tissue specificity

Highly expressed in all adult nuclei. Ref.2

Post-translational modification

Acetylation is generally linked to gene activation By similarity.

Methylation at Lys-5 is linked to gene activation. Methylation at Lys-10 is linked to gene repression By similarity.

Sequence similarities

Belongs to the histone H3 family.
