This opens great opportunities for studying combinatorial binding patterns among a set of TFs active in a particular cellular condition, which is a key component for understanding the interaction between TFs in gene regulation.<\/jats:p>\n               <jats:p>Results: As a first step to the identification of combinatorial binding patterns, we develop statistical methods to detect clustering and ordering patterns among binding sites (BSs) of a pair of TFs. Testing procedures based on Ripley\u2019s K-function and its generalizations are developed to identify binding patterns from large collections of BSs in ChIP-Seq data. We have applied our methods to the ChIP-Seq data of 91 pairs of TFs in mouse embryonic stem cells. Our methods have detected clustering binding patterns between most TF pairs, which is consistent with the findings in the literature, and have identified significant ordering preferences, relative to the direction of target gene transcription, among the BSs of seven TFs. More interestingly, our results demonstrate that the identified clustering and ordering binding patterns between TFs are associated with the expression of the target genes. These findings provide new insights into co-regulation between TFs.<\/jats:p>\n               <jats:p>Availability and implementation: See \u2018www.stat.ucla.edu\/\u223czhou\/TFKFunctions\/\u2019 for source code.<\/jats:p>\n               <jats:p>Contact: \u00a0zhou@stat.ucla.edu<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary Data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btu303","type":"journal-article","created":{"date-parts":[[2014,5,1]],"date-time":"2014-05-01T00:42:34Z","timestamp":1398904954000},"page":"2263-2271","source":"Crossref","is-referenced-by-count":7,"title":["Detecting clustering and ordering binding patterns among transcription factors via point process models"],"prefix":"10.1093","volume":"30","author":[{"given":"Maria","family":"Cha","sequence":"first","affiliation":[{"name":"1Department of Statistics, University of California, Los Angeles, CA 90095, USA"}]},{"given":"Qing","family":"Zhou","sequence":"additional","affiliation":[{"name":"1Department of Statistics, University of California, Los Angeles, CA 90095, USA"}]}],"member":"286","published-online":{"date-parts":[[2014,4,29]]},"reference":[{"key":"2023012711522835100_btu303-B1","doi-asserted-by":"crossref","first-page":"329","DOI":"10.1111\/1467-9574.00144","article-title":"Non- and semi-parametric estimation of interaction in inhomogeneous point patterns","volume":"54","author":"Baddeley","year":"2000","journal-title":"Stat.
