Until now, models for predicting genome-wide nucleosome occupancy have assumed that the DNA associations of neighboring nucleosomes on the genome are independent. We present a new model that relaxes this independence assumption by modeling interactions between adjacent nucleosomes.<\/jats:p>\n Results: We show that modeling interactions between adjacent nucleosomes improves genome-wide nucleosome occupancy predictions in an in vitro system that includes only nucleosomes and purified DNA, where the resulting model has a preference for short spacings (linkers) of less than 20 bp in length between neighboring nucleosomes. Since nucleosome occupancy in vitro depends only on properties intrinsic to nucleosomes, these results suggest that the interactions we find are intrinsic to nucleosomes and do not depend on other factors, such as transcription factors and chromatin remodelers. We also show that modeling these intrinsic interactions significantly improves genome-wide predictions of nucleosome occupancy in vivo.<\/jats:p>\n Contact: \u00a0eran.segal@weizmann.ac.il<\/jats:p>\n Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btp216","type":"journal-article","created":{"date-parts":[[2009,5,28]],"date-time":"2009-05-28T15:48:54Z","timestamp":1243525734000},"page":"i348-i355","source":"Crossref","is-referenced-by-count":17,"title":["Modeling interactions between adjacent nucleosomes improves genome-wide predictions of nucleosome occupancy"],"prefix":"10.1093","volume":"25","author":[{"given":"Shai","family":"Lubliner","sequence":"first","affiliation":[{"name":"1 Department of Computer Science and Applied Mathematics and 2Department of Molecular Cell Biology, Weizmann Institute of Science, Rehovot, Israel"}]},{"given":"Eran","family":"Segal","sequence":"additional","affiliation":[{"name":"1 Department of Computer Science and Applied Mathematics and 2Department of Molecular Cell Biology, Weizmann Institute of Science, Rehovot, Israel"},{"name":"1 Department of Computer Science and Applied Mathematics and 2Department of Molecular Cell Biology, Weizmann Institute of Science, Rehovot, Israel"}]}],"member":"286","published-online":{"date-parts":[[2009,5,27]]},"reference":[{"key":"2023013112015229800_B1","doi-asserted-by":"crossref","first-page":"1105","DOI":"10.1038\/nsmb1334","article-title":"A charged and contoured surface on the nucleosome regulates chromatin compaction","volume":"14","author":"Chodaparambil","year":"2007","journal-title":"Nat.
