The glucagon receptor is a 62 kDa protein that is activated by glucagon and is a member of the class B G-protein coupled family of receptors, coupled to G alpha i, Gs and to a lesser extent G alpha q. Stimulation of the receptor results in activation of adenylate cyclase and increased levels of intracellular cAMP. In humans, the glucagon receptor is encoded by the GCGR gene.
