Antibodies are purified by protein A and peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nGlucose homeostasis is regulated by hormones and cellular energy status. Elevations of blood glucose during feeding stimulate insulin release from pancreatic β-cells through a glucose sensing pathway. Feeding also stimulates release of gut hormones such as glucagon-like peptide-1 (GLP-1), which further induces insulin release, inhibits glucagon release and promotes β-cell viability. CREB-dependent transcription likely plays a role in both glucose sensing and GLP-1 signaling (1). The protein CRTC2 (CREB-regulated transcription coactivator 2)\/TORC2 (transducer of regulated CREB activity 2) functions as a CREB co-activator (2,3) and is implicated in mediating the effects of these two pathways (4). In quiescent cells, CRTC2\/TORC2 is phosphorylated at Ser171 and becomes sequestered in the cytoplasm via an interaction with 14-3-3 proteins. Glucose and gut hormones lead to the dephosphorylation of CRTC2\/TORC2 and its dissociation from 14-3-3 proteins. Dephosphorylated CRTC2\/TORC2 enters the nucleus to promote CREB-dependent transcription. CRTC2\/TORC2 plays a key role in the regulation of hepatic gluconeogenic gene transcription in response to hormonal and energy signals during fasting (5). CRTC2\/TORC2-related proteins CRTC1\/TORC1 and CRTC3\/TORC3 also act as CREB co-activators (2,3). CRTC1\/TORC1, CRTC2\/TORC2 and CRTC3\/TORC3 associate with the HTLV Tax protein to promote Tax-dependent transcription of HTLV-1 long terminal repeats (6,7). CRTC1\/TORC1 is highly phosphorylated at Ser151 in mouse hypothalamic cells under basal conditions (8). When these cells are exposed to cAMP or a calcium activator, CRTC1\/TORC1 is dephosphorylated and translocates into the nucleus (8). CRTC1\/TORC1 is essential for energy balance and fertility (8).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCREB regulated transcription coactivator 3; CREB-regulated transcription coactivator 3; CRTC3; FLJ21868; TORC-3; TORC3; Transducer of CREB protein 3; transducer of regulated cAMP response element-binding protein (CREB) 3; Transducer of regulated cAMP response element-binding protein 3; transducer of regulated CREB protein 3\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H R\nSENSITIVITY: Endogenous\nMW (kDa): 76-78\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46798015594665,"sku":"2768S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-2768s","provider":"Iright","version":"1.0","type":"link"}
