Heritable chromatin structure: mapping "memory" in histones H3 and H4.
Telomeric position effect in Saccharomyces cerevisiae is a chromatin-mediated phenomenon in which telomere proximal genes are repressed (silenced) in a heritable, but reversible, fashion. Once a transcriptional state (active or silenced) is established, however, there is a strong tendency for that state to be propagated. Twenty-five years ago, H. Weintraub and colleagues suggested that such her...

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: 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 کاملHistones of Genetically Active and Inactive Chromatin
It has frequently been proposed that a variation in the relative content of lysine-rich, moderately lysine-rich, and arginine-rich histones might provide a mechanism by which specific portions of the genome may be genetically regulated. This possibility was investigated by comparing the electrophoretic pattern of these three fractions in cells differing markedly in their content of genetically ...
