Reader writer complex histones
WebHistone acetylation marks are written by histone acetyltransferases (HATs) and read by bromodomains (BrDs), and less commonly by other protein modules. These proteins regulate many transcription-mediated biological processes, and their aberrant activities are correlated with several human diseases. WebAug 30, 2024 · Readers are the proteins that detect and respond to these modifications, causing the DNA to be more or less tightly wrapped around the histone protein. Any of these proteins could be inhibited or activated to affect changes in epigenetic modifications. Old School: Writing and Erasing
