Chromatin structure imposes significant obstacles on all aspects of transcription that are
mediated by RNA polymerase II. The dynamics of chromatin structure are tightly regulated …

Histone acetylation regulates many cellular processes, and specific acetylation marks, either
singly or in combination, produce distinct outcomes. For example, the acetylation pattern on …

Histone acetylation is a ubiquitous hallmark of transcription, but whether the link between
histone acetylation and transcription is causal or consequential has not been addressed …

Networks have become a key approach to understanding systems of interacting objects,
unifying the study of diverse phenomena including biological organisms and human …

The organization of eukaryotic chromatin has a major impact on all nuclear processes
involving DNA substrates. Gene expression is affected by the positioning of individual …

Gene transcription by RNA polymerase II is regulated by activator proteins that recruit the
coactivator complexes SAGA (Spt–Ada–Gcn5–acetyltransferase), and transcription factor IID …

Here we review recent advances in understanding the regulation of mRNA synthesis in
Saccharomyces cerevisiae. Many fundamental gene regulatory mechanisms have been …

Chromatin structure creates barriers for each step in eukaryotic transcription. Here we
discuss how the activities of two major classes of chromatin-modifying complexes, ATP …

Covalent modifications of the amino termini of the core histones in nucleosomes have
important roles in gene regulation. Research in the past two years reveals these …

Bromodomains, an extensive family of evolutionarily conserved protein modules originally
found in proteins associated with chromatin and in nearly all nuclear histone …
