G蛋白偶聯受體(G Protein-Coupled Receptors,GPCRs)是一大類膜蛋白受體的統稱。這類受體的共同點是其立體結構中都有7個跨膜α螺旋,且其肽鏈的C端和連接第5和第6個跨膜螺旋的胞內環上都有G蛋白(鳥苷酸結合蛋白)的結合位點。研究顯示G蛋白偶聯受體只見于真核生物之中,而且參與了很多細胞信號轉導過程。在這些過程中,G蛋白偶聯受體能結合細胞周圍環境中的化學物質并激活細胞內的一系列信號通路,最終引起細胞狀態的改變。已知的與G蛋白偶聯受體結合的配體包括氣味,費洛蒙,激素,神經遞質,趨化因子等等。這些配體可以是小分子的糖類,脂質,多肽,也可以是蛋白質等生物大分子。一些特殊的G蛋白偶聯受體也可以被非化學性的刺激源激活,例如在感光細胞中的視紫紅質可以被光所激活。與G蛋白偶聯受體相關的疾病為數眾多,并且大約40%的現代藥物都以G蛋白偶聯受體作為靶點。
I. Background
GLP1R binds specifically the glucagon-like peptide-1 (GLP1) and has much lower affinity for related peptides such as the gastric inhibitory polypeptide and glucagon.

GLP1R is known to be expressed in pancreatic beta cells. Activated GLP1R stimulates the adenylyl cyclase pathway which results in increased insulin synthesis and release of insulin. Consequently, GLP1R has been suggested as a potential target for the treatment of diabetes.GLP1R is also expressed in the brain where it is involved in the control of appetite. Furthermore, mice which over express GLP1R display improved memory and learning.

Ⅳ.Representative Data

Figure 1. GLP-1 (7-37)-induced concentration-dependent stimulation of intracellular luciferase in HEK293/GLP1R/Luc and HEK293 cells.

After stimulation with GLP1 receptor agonist, GLP-1 (7-37), the cells are checked with BrightGlo?Luciferase Assay System and the relative luminescence units (RLU) of

luciferase were recorded on a FlexStation. The RLU were plotted against the log of the cumulative doses (10 -fold dilution) of GLP-1 (7-37) (Mean ± SD, n = 2). The EC50 of GLP-1 (7-37) co-expressing with Luc

in HEK293 cells was 4.91 nM.
