Epigenetic Regulation by Histone Methylation and Histone …
Webb3 apr. 2024 · Histones undergo a number of post-translational modifications, including methylation and acetylation, which regulate transcription and gene expression. The enzymes responsible for adding or removing these epigenetic marks are often referred to as “writers” and “erasers”, respectively. WebbHistone modifications are an early indicator of epigenetic regulation, and one way to study this phenomenon is via chromatin immunoprecipitation (ChIP).

Webb15 dec. 2024 · The histone methyltransferase enhancer of zeste homolog 2 (EZH2) is the enzymatic catalytic subunit of the polycomb-repressive complex 2 (PRC2) that can alter gene expression by trimethylating lysine 27 on histone 3 (H3K27). EZH2 is involved in global transcriptional repression, mainly targeting tumor-suppressor genes.
