WebSep 30, 2024 · This chain structure of the histone tail provides an optimal binding site. The histone readers are a group of diverse proteins that recognize and bind specifically to the N-tail of histones leading to chromatin remodeling or involving in gene expression or joining as chromatin architectural proteins. WebDec 15, 2011 · Histone tails are the most common sites of post-translational modifications. Tail modifications alter both inter and intra nucleosomal interactions to disrupt the condensed chromatin structure, thereby playing crucial role in gene access.
