G蛋白偶联受体(G Protein-Coupled Receptors,GPCRs)是一大类膜蛋白受体的统称,也是数量最多的细胞表面受体。这些受体的共同特点是其立体结构中都有七个跨膜α螺旋,且其肽链的C端和连接(从肽链N端数起)第5和第6个跨膜螺旋的胞内环(第三个胞内环)上都有G蛋白(鸟苷酸结合蛋白)的结合位点。 G蛋白偶联受体存在于...
G蛋白偶联受体(G protein-coupled receptors,GPCR)是细胞表面的一种跨膜蛋白,它在信号转导过程中起着至关重要的作用。这些受体能够识别和结合多种不同的信号分子,包括激素、神经递质、光、气味等,从而触发一系列的生物化学反应。 GPCR的结构可以分为三个部分:胞外域、跨膜域和胞内域。胞外域负责识别和结合信号分子...
G-protein-coupled receptors (GPCRs) are the largest and most diverse group of membrane receptors in eukaryotes. G proteins are specialized proteins with the ability to bind the nucleotides guanosine triphosphate (GTP) and guanosine diphosphate (GDP). The G proteins that associate with GPCRs are h...

合成生物催化剂摘译自https://www.nature.com/articles/s41467-022-31357-6真核细胞使用G蛋白偶联受体(G-protein-coupled receptors, GPCRs)来感知从化合物到光的各种信号。 利用GPCRs的传感能力可能对生物技术产生深远的影响,使大量配体的特异性检测成为可能。
G protein-coupled receptors and heterotrimeric G proteins can diffuse laterally in the plasma membrane such that one receptor can catalyze the activation (GDP/GTP exchange) of multiple G proteins. In some cases, these processes are fast enough to support molecular signal amplification, where a ...
