G proteins couple receptors of extracellular signals to intracellular signaling pathways. The G protein alpha subunit binds guanyl nucleotide and is a weak GTPase. A set of residues that are unique to G-alpha as compared to its ancestor the Arf-like family form a ring of residues centered on the nucleotide binding site [3]. A Ggamma is found fused to an inactive Galpha in the Dictyostelium protein gbqA [3].

This domain represents the C-terminal region of the Neuromedin-U receptor 2, a rhodopsin-like GPCR member. It contains two potential casein kinase II phosphorylation sites at threonines residues and one protein kinase C phosphorylation site at a serine residue, which are important to regulate the receptor functionality. This receptor is predominantly expressed in the central nervous system, particularly in the medulla oblongata, pontine reticular formation, spinal cord and thalamus, as its physiological roles are related to modulation of sensory function, neuroendocrine control, food intake as well as with circadian rhythm. However, peripheral expression of this receptor has been determined and includes kidney (medulla), lung and trachea [1-3].
