Examination of the tissue expression profiles revealed that mCES2 is expressed in the liver, kidney, small intestine, brain, thymus, lung, adipose tissue and testis. When the mCES2 promoter was cloned and characterized, it was revealed that Sp1 (specificity protein 1) and Sp3 could bind to a GC box, that USF (upstream stimulatory factor) 1 could bind to an E (enhancer) box, and that Sp1 could bind to an NF\u03baB (nuclear factor \u03baB) element in the mCES2 promoter. Co-transfection assays showed that all of these transcription factors contributed synergistically to transactivation of the mCES2 promoter. Taken together, our results indicate that Sp1, Sp3 and USF1 are indispensable factors for transactivation of the mCES2 gene promoter. To our knowledge, this is the first study in which transcription factors that interact with a CES2 family gene have been identified. The results of the present study have provided some clues for understanding the molecular mechanisms regulating mCES2 gene expression, and should be useful for studies aimed at elucidation of physiological functions of mCES2.<\/jats:p>","DOI":"10.1042\/bj20040765","type":"journal-article","created":{"date-parts":[[2004,11,9]],"date-time":"2004-11-09T11:43:29Z","timestamp":1100000609000},"page":"101-110","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Synergistic role of specificity proteins and upstream stimulatory factor 1 in transactivation of the mouse carboxylesterase 2\/microsomal acylcarnitine hydrolase gene promoter"],"prefix":"10.1042","volume":"384","author":[{"given":"Tomomi","family":"FURIHATA","sequence":"first","affiliation":[{"name":"Laboratory of Pharmacology and Toxicology, Graduate School of Pharmaceutical Sciences, Chiba University, Chiba 260-8675, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masakiyo","family":"HOSOKAWA","sequence":"additional","affiliation":[{"name":"Laboratory of Pharmacology and Toxicology, Graduate School of Pharmaceutical Sciences, Chiba University, Chiba 260-8675, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsuo","family":"SATOH","sequence":"additional","affiliation":[{"name":"Laboratory of Pharmacology and Toxicology, Graduate School of Pharmaceutical Sciences, Chiba University, Chiba 260-8675, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kan","family":"CHIBA","sequence":"additional","affiliation":[{"name":"Laboratory of Pharmacology and Toxicology, Graduate School of Pharmaceutical Sciences, Chiba University, Chiba 260-8675, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"288","published-online":{"date-parts":[[2004,11,9]]},"reference":[{"key":"2021112212591398300_B1","doi-asserted-by":"crossref","first-page":"821","DOI":"10.1042\/bj3130821","article-title":"Cloning and sequencing of rat liver carboxylesterase ES-4 (microsomal palmitoyl-CoA hydrolase)","volume":"313","author":"Robbi","year":"1996","journal-title":"Biochem.
