Chromatin remodeling is essential for proper adaptation to extracellular stimuli. The p38-related Hog1 SAPK is an important regulator of transcription that mediates chromatin remodeling upon stress. Hog1 targets the RSC chromatin remodeling complex to stress-responsive genes and rsc deficient cells display reduced induction of gene expression. Here we show that the absence of H3K4 methylation, ...

ATP-dependent chromatin remodeling activities participate in the alteration of chromatin structure during gene regulation. All have DNA- or chromatin-stimulated ATPase activity and many can alter the structure of chromatin; however, the means by which they do this have remained unclear. Here we describe a novel activity for ATP-dependent chromatin remodeling activities, the ability to generate ...

Introduction Chromatin modifications and epigenetics are important pathogenesis mechanisms leading to various neurologic psychiatric disorders including epilepsy, drug addictions, depression, autistic spectrum, learning disabilities schizophrenia. Recently, the disruption of chromatin remodeling BAF complex has been linked several neurodevelopmental syndromes, commonly referred as PBAFopathies....

A central problem in the regulation of eukaryotic gene expression is understanding how gene-specific transcriptional activators orchestrate the recruitment of the myriad proteins that are required for transcription initiation. An emerging view indicates that activators must first target two types of chromatin remodeling enzyme to the promoter region: an ATP-dependent SWI/SNF-like complex and a ...

DNA repair in eukaryotic cells takes place in the context of chromatin, where DNA, including damaged DNA, is tightly packed into nucleosomes and higher order chromatin structures. Chromatin intrinsically restricts accessibility of DNA repair proteins to the damaged DNA and impacts upon the overall rate of DNA repair. Chromatin is highly responsive to DNA damage and undergoes specific remodeling...
