Product Details

Description	Mammalian cell-expressed recombinant human GCGR is a partial length protein tagged with a 10xHis motif at the N-terminus and a Myc motif at the C-terminus. Its DNA sequence corresponds to amino acids 26-136 of the human GCGR. This GCGR protein has high purity, greater than 95% determined by SDS-PAGE. It migrated to the molecular weight band of about 32 kDa on the gel. Its endotoxin content is less than 1.0 EU/ug measured by the LAL method. It is also biologically active and its activity has been validated through a functional ELISA by binding to the anti-GCGR antibody. And it is in stock now. GCGR, a member of class B GPCR, combines with the natural ligand glucagon to regulate blood glucose homeostasis. It is an important drug target for type II diabetes. A series of drugs targeting GCGR have been developed to relieve hyperglycemia in diabetic patients, including GCGR antagonists, antibodies, and antisense oligonucleotides of GCGR.

Target Background

Function (From Uniprot)	G-protein coupled receptor for glucagon that plays a central role in the regulation of blood glucose levels and glucose homeostasis. Regulates the rate of hepatic glucose production by promoting glycogen hydrolysis and gluconeogenesis. Plays an important role in mediating the responses to fasting. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase. Promotes activation of adenylate cyclase. Besides, plays a role in signaling via a phosphatidylinositol-calcium second messenger system.

PMID: 28586439 Data suggest that GCGR activation proceeds via a mechanism in which transmembrane helix 6 (TM6) is held in an inactive conformation by a conserved polar core and a hydrophobic lock (involving intracellular loop 3, IC3); mutations in the corresponding polar core of GCGR disrupt these inhibitory elements, allow TM6 to swing outward, and induce constitutive G protein signaling. PMID: 28356352 The activation of the GCGR is characterized by the outward movement of the intracellular side of helix VI. In the active state of the GCGR, the Arg173(2.46)-Ser350(6.41) and Glu245(3.50)-Thr351(6.42) hydrogen bonds break, and the chi1 rotamer of Phe322(5.54) changes from perpendicular to parallel to helix VI.
