Architecture of the SWI/SNF-nucleosome complex.
The SWI/SNF complex disrupts and mobilizes chromatin in an ATP-dependent manner. SWI/SNF interactions with nucleosomes were mapped by DNA footprinting and site-directed DNA and protein cross-linking when SWI/SNF was recruited by a transcription activator. SWI/SNF was found by DNA footprinting to contact tightly around one gyre of DNA spanning approximately 50 bp from the nucleosomal entry site ...
متن کاملActivation domains drive nucleosome eviction by SWI/SNF.
ATP-dependent chromatin remodeling complexes play a critical role in chromatin dynamics. A large number of in vitro studies have pointed towards nucleosome sliding as the principal remodeling outcome of SWI/SNF action, whereas few have described histone octamer transfer as the principal outcome. In contrast, recent in vivo studies have linked the activity of SWI/SNF to histone eviction in trans...
متن کاملLinker histone H1 modulates nucleosome remodeling by human SWI/SNF.
Chromatin, a combination of nucleosomes and linker histones, inhibits transcription by blocking polymerase movement and access of factors to DNA. ATP-dependent remodeling complexes such as SWI/SNF and RSC alter chromatin structure to increase or decrease this repression. To further our understanding of how human SWI/SNF (hSWI/SNF) "remodels" chromatin we examined the octamer location, nature, a...
متن کاملa contrastive study of rhetorical functions of citation in iranian and international elt scopus journals
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
assessment of deep word knowledge in elementary and advanced iranian efl learners: a comparison of selective and productive wat tasks
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
