An N-terminal region of Caenorhabditis elegans RGS proteins EGL-10 and EAT-16 directs inhibition of G(alpha)o versus G(alpha)q signaling.

Abstract

Regulator of G protein signaling (RGS) proteins contain an RGS domain that inhibits G(alpha) signaling by activating G(alpha) GTPase activity. Certain RGS proteins also contain a Ggamma-like (GGL) domain and a poorly characterized but conserved N-terminal region. We assessed the functions of these subregions in the Caenorhabditis elegans RGS proteins EGL-10… (More)
