WebRegulation of chromatin by histone modifications Chromatin is not an inert structure, but rather an instructive DNA scaffold that can respond to external cues to regulate the many uses of DNA. A principle component of chromatin that plays a key role in this regulation is the modification of histones. WebHistones, the proteins around which nucleosomes are built (Fig. 1), can interact with a range of proteins to regulate gene transcription and to maintain genome stability in processes such as replication, recombination, cell cycle progression, and DNA repair.All histone proteins are capable of taking on a wide variety of reversible posttranslational modifications, and … WebJun 12, 2014 · Histone modifications include methylation, acetylation, and monoubiquitination, with involvement of enzymes including histone methyltransferases, histone acetyltransferases/deacetylases, and … ct chet fund
