WebbHistone chaperone proteins have prominent roles in facilitating these processes as well as in replacing old histones with new canonical histones or histone variants during the process of histone exchange. Recent structural, biophysical and biochemical studies have begun to shed light on the molecular mechanisms whereby histone chaperones ... WebbHistone acetylation influences chromatin structure in several ways. First, it can provide a tag for the binding of proteins that contain areas which recognize the acetylated tails. Secondly, it can block the function of chromatin remodelers. [12] Thirdly, it neutralizes the positive charge on lysines. [12]
