Nucleosome core particle treated with oxaliplatin
Structural highlights
FunctionH32_XENLA 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. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedX-ray crystallographic and biochemical investigation of the reaction of cisplatin and oxaliplatin with nucleosome core particle and naked DNA reveals that histone octamer association can modulate DNA platination. Adduct formation also occurs at specific histone methionine residues, which could serve as a nuclear platinum reservoir influencing adduct transfer to DNA. Our findings suggest that the nucleosome center may provide a favorable target for the design of improved platinum anticancer drugs.
