G蛋白（英语：G Protein）是指鸟苷酸结合蛋白。它含有一个鸟苷酸结合结构域，由α、β、γ三个亚基组成。激活状态下的G蛋白可以激活腺苷酸环化酶系统（AC系统）产生第二信使cAMP，从而产生进一步的生物学效应。

G蛋白激活腺苷酸环化酶，该酶催化ATP生成cAMP。 2017级专外有声 Cyclic AMP (cAMP) is produced when the receptor protein activates another membrane-bound protein called a G protein. 当受体蛋白激活另一种称为G蛋白的膜结合蛋白时，就会产生环磷酸腺苷 (cAMP)。中文百科 G蛋白 G protein （重定向自G Proteins） G蛋白（英语：G Protein）是指鸟苷酸结合蛋白。它含有一个鸟苷酸结合结构域，由α、β、γ三个亚基组成。激活状态下的G蛋白可以激活腺苷酸环化酶系统（AC系统）产生第二信使cAMP，从而产生进一步的生物学效应。英语百科 G protein G蛋白（重定向自G Proteins） G proteins, also known as guanine nucleotide-binding proteins, are a family of proteins that act as molecular switches inside cells, and are involved in transmitting signals from a variety of stimuli outside a cell to its interior. Their activity is regulated by factors that control their ability to bind to and hydrolyze guanosine triphosphate (GTP) to guanosine diphosphate (GDP). When they are bound to GTP, they are 'on', and, when they are bound to GDP, they are 'off'. G proteins belong to the larger group of enzymes called GTPases.
