Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Target Data

Function 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.

  2. work toward the mapping of interactions between the polypeptide hormone glucagon and the glucagon receptor PMID: 28508109
  3. 3.0 A crystal structure of full-length GCGR containing both the extracellular domain and transmembrane domain in an inactive conformation PMID: 28514451
  4. This work suggests that RAMP2 may modify the agonist activity and trafficking of the GCGR, with potential relevance to production of new peptide analogs with selective agonist activities. PMID: 28586439
  5. 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
  6. 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. PMID: 27094704
  7. In the glucagon receptor (GCGR) and glucagon-like peptide-1 receptor (GLP-1R), the extracellular domain is required for signaling even when the hormone is covalently linked to the transmembrane domain. PMID: 27226600
  8. 2.5 A crystal structure of human GCGR in complex with the antagonist MK-0893, which is found to bind to an allosteric site outside the seven transmembrane helical bundle in a position between TM6 and TM7 extending into the lipid bilayer PMID: 27111510
  9. Molecular dynamics and disulfide crosslinking studies suggest that apo-GCGR can adopt both an open and closed conformation associated with extensive contacts between the ECD and 7TM domain. Glucagon binds to GCGR by a conformational selection mechanism. PMID: 26227798

  15. F22, V23, M27, and D15 of GCGR are the most important residues for glucagon binding. PMID: 22893257
  16. in addition to activation of the classic cAMP/protein kinase A (PKA) pathway, activation of GCGR also induced beta-catenin stabilization and activated beta-catenin-mediated transcription PMID: 22438981
  17. analysis of glucagon receptor antagonists with reduced molecular weight and lipophilicity PMID: 22119466

  20. The [Ca2+] response is induced by glucagon mainly via the coupling of GCGR to the Galphaq/11 and Galphai/o proteins. PMID: 19903011
  21. The Gly40Ser polymorphism of the GCGR gene is associated with higher risk of hypertension and with enhanced proximal tubular sodium reabsorption. PMID: 11692154
  22. Gly40Ser mutation in the glucagon receptor gene is not associated with type 2 diabetes in a Brazilian population, but a reduction of insulin secretion was observed in Gly40Ser carriers. PMID: 11961492
