Previous studies evaluated the interactions locally, thereby ignoring the competitive effects of different substructures or domains, but this could lead to high false-positive estimation, calling for a computational method that presents more predictive power.<\/jats:p><jats:p>Results: A statistical model, termed Global optimization-based InFerence of chemogenomic features from drug\u2013Target interactions, or GIFT, is proposed herein to evaluate substructure-domain interactions globally such that all substructure-domain contributions to drug\u2013target interaction are analyzed simultaneously. Combinations of different chemical substructures were included since they may function as one unit. When compared to previous methods, GIFT showed better interpretive performance, and performance for the recovery of drug\u2013target interactions was good. Among 53 known drug\u2013domain interactions, 81% were accurately predicted by GIFT. Eighteen of the top 100 predicted combined substructure-domain interactions had corresponding drug\u2013target structures in the Protein Data Bank database, and 15 out of the 18 had been proved. GIFT was then implemented to predict substructure-domain interactions based on drug repositioning. For example, the anticancer activities of tazarotene, adapalene, acitretin and raloxifene were identified. In summary, GIFT is a global chemogenomic inference approach and offers fresh insight into drug\u2013target interactions.<\/jats:p><jats:p>Availability and implementation: The source codes can be found at http:\/\/bioinfo.au.tsinghua.edu.cn\/software\/GIFT.<\/jats:p><jats:p>Contact: \u00a0shaoli@mail.tsinghua.edu.cn<\/jats:p><jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btv181","type":"journal-article","created":{"date-parts":[[2015,3,30]],"date-time":"2015-03-30T00:12:02Z","timestamp":1427674322000},"page":"2523-2529","source":"Crossref","is-referenced-by-count":25,"title":["Global optimization-based inference of chemogenomic features from drug\u2013target interactions"],"prefix":"10.1093","volume":"31","author":[{"given":"Songpeng","family":"Zu","sequence":"first","affiliation":[{"name":"1 MOE Key Laboratory of Bioinformatics and Bioinformatics Division, TNLIST\/Department of Automation, Tsinghua University, Beijing 100084, China and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ting","family":"Chen","sequence":"additional","affiliation":[{"name":"1 MOE Key Laboratory of Bioinformatics and Bioinformatics Division, TNLIST\/Department of Automation, Tsinghua University, Beijing 100084, China and"},{"name":"2 Molecular and Computational Biology Program, Department of Biological Sciences, University of Southern California, Los Angeles, CA 90089, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shao","family":"Li","sequence":"additional","affiliation":[{"name":"1 MOE Key Laboratory of Bioinformatics and Bioinformatics Division, TNLIST\/Department of Automation, Tsinghua University, Beijing 100084, China and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2015,3,29]]},"reference":[{"key":"2023051308490992600_btv181-B1","doi-asserted-by":"crossref","first-page":"D138","DOI":"10.1093\/nar\/gkh121","article-title":"The Pfam protein families database","volume":"32","author":"Bateman","year":"2004","journal-title":"Nucleic Acids.
