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.[1] 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.[2][3]

Glucagon receptors are mainly expressed in liver and in kidney with lesser amounts found in heart, adipose tissue, spleen, thymus, adrenal glands, pancreas, cerebral cortex, and gastrointestinal tract.

glucagon/glucagon receptor (blue) with glucagon bound(pink)

The 3D crystallographic structures of the seven transmembrane helical domain (7TM)[4] and the extracellular domain (ECD)[5] and an electron microscopy (EM) map of full length glucagon receptor[6] have been determined.

Clinical significance

A missense mutation in the GCGR gene is associated with diabetes mellitus type 2.[7]

Inactivating mutation of glucagon receptor in humans causes resistance to glucagon and is associated with pancreatic alpha cell hyperplasia, nesidioblastosis, hyperglucagonemia, and pancreatic neuroendocrine tumors.[8]
