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

G-protein gamma like domains (GGL) are found in the gamma subunit of the heterotrimeric G protein complex and in regulators of G protein signaling (RGS) proteins [1]. It is also found fused to an inactive Galpha in the Dictyostelium protein gbqA [2]. G-gamma likely shares a common origin with the helical N-terminal unit of G-beta [2]. All organisms that posses a G-beta possess a G-gamma [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].
