靶點詳情

功能：

Core component of nucleosome. 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.

2. Data suggest post-translational modifications of histones, trimethylation of lysine 36 in H3 (H3K36me3) and acetylation of lysine 16 in H4 (H4K16ac), have roles in DNA damage repair; H3K36me3 stimulates H4K16ac upon DNA double-strand break; SETD2, LEDGF, and KAT5 are required for these epigenetic changes.
