This domain is found in RGS9 (Class C) regulator of G-protein signalling (RGS) protein present in Mus musculus. RGS proteins attenuate heterotrimeric G-protein signalling by enhancing the intrinsic GTPase activity of G-alpha subunits and are vital for proper signal transduction kinetics. The domain is referred to as DEP helical extension (DHEX) because it is located next to N-terminal Dishevelled/Egl-10/Pleckstrin homology (DEP) domain. Both the DEP and DHEX domains are necessary, but not sufficient, to bind anchoring proteins such as RGS9 anchor protein. DHEX has no close structural homologs [1]. This domain is also found in regulator of G-protein signaling 7 (RGS7), the crystal structure of which has been solved [2].	Domain

The DEP domain [1] is responsible for mediating intracellular protein targeting and regulation of protein stability in the cell [2-3]. The DEP domain is present in a number of signaling molecules, including Regulator of G protein Signaling (RGS) proteins, and has been implicated in membrane targeting [4-5]. New findings in yeast, however, demonstrate a major role for a DEP domain in mediating the interaction of an RGS protein to the C-terminal tail of a GPCR, thus placing RGS in close proximity with its substrate G protein alpha subunit [6-7].

This entry represents the extracellular domain of GPR158 (also known as metabotropic glycine receptor, mGlyR) and GRP179. This domain has a Cache-like fold which participates in ligand recognition and also mediates dimerization and stability of the dimer [2]. GPR158 functions in cognition, stress-induced mood control, and synaptic development.	Domain

This is a domain of seven transmembrane regions that forms the C-terminus of some subclass 3 G-coupled-protein receptors. It is often associated with a downstream cysteine-rich linker domain, NCD3G Pfam:PF07562, which is the human sweet-taste receptor, and the N-terminal domain, ANF_receptor Pfam:PF01094. The seven TM regions assemble in such a way as to produce a docking pocket into which such molecules as cyclamate and lactisole have been found to bind and consequently confer the taste of sweetness [1].
