The model organism Arabidopsis thaliana contains a restricted set of heterotrimeric G-protein subunits, with only one canonical Galpha subunit (AtGPA1), one Gbeta subunit (AtAGB1), and two Ggamma subunits (AtAGG1 and AtGG2) identified. We have identified a novel additional component of heterotrimeric G-protein signaling in the A. thaliana genome, regulator of G-protein signaling-1 (AtRGS1). This protein has the predicted topology and structure of a G-protein-coupled receptor in that it contains… CONTINUE READING
