Their gene products form a complex that has become the focus of many signal transduction researchers. The TSC1\u2013TSC2 (hamartin\u2013tuberin) complex, through its GAP (GTPase-activating protein) activity towards the small G-protein Rheb (Ras homologue enriched in brain), is a critical negative regulator of mTORC1 (mammalian target of rapamycin complex 1). As mTORC1 activity controls anabolic processes to promote cell growth, it is exquisitely sensitive to alterations in cell growth conditions. Through numerous phosphorylation events, the TSC1\u2013TSC2 complex has emerged as the sensor and integrator of these growth conditions, relaying signals from diverse cellular pathways to properly modulate mTORC1 activity. In the present review we focus on the molecular details of TSC1\u2013TSC2 complex regulation and function as it relates to the control of Rheb and mTORC1.<\/jats:p>","DOI":"10.1042\/bj20080281","type":"journal-article","created":{"date-parts":[[2008,5,14]],"date-time":"2008-05-14T10:20:31Z","timestamp":1210760431000},"page":"179-190","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":1090,"title":["The TSC1\u2013TSC2 complex: a molecular switchboard controlling cell growth"],"prefix":"10.1042","volume":"412","author":[{"given":"Jingxiang","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Genetics and Complex Diseases, Harvard School of Public Health, Boston, MA 02115, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brendan\u00a0D.","family":"Manning","sequence":"additional","affiliation":[{"name":"Department of Genetics and Complex Diseases, Harvard School of Public Health, Boston, MA 02115, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","published-online":{"date-parts":[[2008,5,14]]},"reference":[{"key":"2021112214182057900_B1","doi-asserted-by":"crossref","first-page":"37","DOI":"10.1038\/ng0992-37","article-title":"Linkage of an important gene locus for tuberous sclerosis to a chromosome 16 marker for polycystic kidney disease","volume":"2","author":"Kandt","year":"1992","journal-title":"Nat.
