Evolution of the Regulators of G-Protein Signaling Multigene Family in Mouse and Human

The regulators of G-protein signaling (RGS) proteins are important regulatory and structural components of G-protein coupled receptor complexes. RGS proteins are GTPase activating proteins (GAPs) of Gi-and Gq-class Galpha proteins, and thereby accelerate signaling kinetics and termination. Here, we mapped the chromosomal positions of all 21 Rgs genes in mouse, and determined human RGS gene structures using genomic sequence from partially...
