【生理學 G蛋白偶合受體】
G蛋白偶合受體（G Protein-Coupled Receptors， GPCRs）
,是一大類膜蛋白受體的統稱。
這類受體的共同點參與了很多細胞訊號傳導過程。
在這些過程中，G蛋白偶合受體能結合細胞周圍環境中的化學物質並活化細胞內的一系列訊號通路，最終引起細胞功能狀態的改變。
G蛋白偶聯受體的下游信號通路有多種。
通過以三磷酸鳥苷(GTP)交換G蛋白上本來結合著的二磷酸鳥苷(GDP)
使G蛋白的α次單位與β、γ次單位分離。
這一過程使得G蛋白變為活化狀態，
並參與下一步的信號傳遞過程。
具體的傳遞通路取決於α次單位的種類
(Gs, Gi, Gq,)其中Gs, Gi分別以由三磷酸腺苷環化產生的環腺苷酸(cAMP),而Gq則已磷脂醯肌醇-4,5-二磷酸(PIP2)水解生成的肌醇三磷酸(IP3)和甘油二酯(DAG)作為次級傳訊者。
