Chromatin: Hanging on to histones
The core histones have long been known to have an important role in the packaging of DNA into nucleosomes. Today, nucleosome assembly is recognized as an integral component of both transcriptional activation and repression [1]. Transcriptional control is mediated through the assembly of extensive nucleoprotein structures containing both conventional transcription factors and architectural facto...
متن کاملProteins: histones and chromatin.
Patrick Cramer is a professor of Biochemistry at the Ludwig Maximilians University of Munich, Germany, and head of the Gene Center Munich. He is a structural biologist who has contributed to our understanding of the structure and function of RNAP II from yeast and its associated factors. In a recent study, his laboratory described the structure of RNAP II in complex with the initiation factor T...
متن کاملChromatin modification: How to put a HAT on the histones
Specific patterns of acetylation of the core histones are associated with specific structures and functions of chromatin. A basis for the specificity of acetylation is now apparent in the recent crystal structures of two acetyltransferases.

متن کاملBlocking by histones of accessibility to DNA in chromatin: addition of histones.
The blocking effect of histones on accessibility of DNA to DNase has been studied by addition of various histones to chromatin in intact or histone-depleted thymus nuclei (those from which all lysine-rich histone was removed and those from which much of the arginine-rich histone was removed) and to deoxyribonucleoprotein (chromatin) extracted from nuclei. In each case lysine-rich histone, weigh...
