Primary Identifier | IPR040759 | Type | Domain |
Short Name | RGS_DHEX |
description | 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 homologues []. |
