Proteins of the regulator of G protein signaling (RGS) family accelerate GTP hydrolysis by the alpha subunits (G(alpha)) of G proteins, leading to rapid recovery of signaling cascades. Many different RGS proteins can accelerate GTP hydrolysis by an individual G(alpha), and GTP hydrolysis rates of different G(alpha)s can be enhanced by the same RGS protein. Consequently, the mechanisms for speci...
PURPOSE To determine the biochemical defects that underlie Axenfeld-Rieger malformations, to determine a functional role for wing 2 in FOXC1, and to understand how mutations in this region disrupt FOXC1 function. METHODS Sequencing DNA from patients with Axenfeld-Rieger malformation resulted in the identification of two novel missense mutations (G165R and R169P) in wing 2 of FOXC1. Site-direc...
Functional asymmetry of G-protein-coupled receptor (GPCR) dimers has been reported for an increasing number of cases, but the molecular architecture of signalling units associated to these dimers remains unclear. Here, we characterized the molecular complex of the melatonin MT₁ receptor, which directly and constitutively couples to G(i) proteins and the regulator of G-protein signalling (RGS) 2...
The R7 family of regulators of G protein signaling (RGS) proteins, comprising RGS6, RGS7, RGS9, and RGS11, regulate neuronal G protein signaling pathways. All members of the R7 RGS form trimeric complexes with the atypical G protein β subunit, Gβ5, and membrane anchor R7BP or R9AP. Association with Gβ5 and membrane anchors has been shown to be critical for maintaining proteolytic stability of t...
Regulator of G protein signaling (RGS) proteins are GTPase-activating proteins (GAP) for G protein alpha-subunits and are thought to be responsible for rapid deactivation of G protein mediated signaling pathway. In this present study, we demonstrate that PA is the most efficient candidate to inhibit GAP activity of RGS4. The functional significance of N-terminus of RGS4 in respose to PA-granted...
