Histone writer
WebbWhat is the role of histone writers? 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. Webb14 nov. 2016 · Histone “Writers” disrupt inter-nucleosome and intra-nucleosome contact by causing chromatin to “relax”, becoming more accessible. For example, acetylation acts by causing a reduction in the electrostatic interaction between negatively charged DNA and the lysine residue, leading to more “open” chromatin formation.

The histone code is a hypothesis that the transcription of genetic information encoded in DNA is in part regulated by chemical modifications (known as histone marks) to histone proteins, primarily on their unstructured ends. Together with similar modifications such as DNA methylation it is part of the epigenetic code. Histones associate with DNA to form nucleosomes, which themselves bundle to form chromatin fibers, which in turn make up the more familiar chromosome. Histones are glob… WebbProteins mediating these dynamic processes are the so-called "readers", "writers", and "erasers" [50, 51].
