Description:
The positioning of nucleosomes within the coding regions of eukaryotic genes is aligned with respect to transcriptional start sites. This organization is likely to influence many genetic processes, requiring access to the underlying DNA. Here, we show that the combined action of Isw1 and Chd1 nucleosome-spacing enzymes is required to maintain this organization. In the absence of these enzymes, regular positioning of the majority of nucleosomes is lost. Exceptions include the region upstream of the promoter, the +1 nucleosome, and a subset of locations distributed throughout coding regions where other factors are likely to be involved. These observations indicate that adenosine triphosphate-dependent remodeling enzymes are responsible for directing the positioning of the majority of nucleosomes within the Saccharomyces cerevisiae genome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3428865/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3428865/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gkikopoulos, Triantaffyllos -- Schofield, Pieta -- Singh, Vijender -- Pinskaya, Marina -- Mellor, Jane -- Smolle, Michaela -- Workman, Jerry L -- Barton, Geoffrey J -- Owen-Hughes, Tom -- 064414/Wellcome Trust/United Kingdom -- 095062/Wellcome Trust/United Kingdom -- G0900740/Medical Research Council/United Kingdom -- R01 GM047867/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2011 Sep 23;333(6050):1758-60. doi: 10.1126/science.1206097.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Centre for Gene Regulation and Expression, College of Life Sciences, University of Dundee, Dundee, DD1 5EH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21940898" target="_blank"〉PubMed〈/a〉
