rgs-2 encodes a regulator of G protein signaling; by homology, RGS-2 is predicted to function as a GTPase-activating protein for heterotrimeric G-protein alpha-subunits, and in vitro RGS-2 can stimulate the GTPase activity of purified GOA-1; in vivo, rgs-2 appears to function redundantly with rgs-1 to regulate egg-laying behavior when animals are refed following starvation; rgs-2 is expressed in pharyngeal and uterine muscles and in a subset of neurons, including neurons in the ventral cord and head- and tail-ganglia.
Enables GTPase activator activity. Predicted to be involved in negative regulation of signal transduction. Expressed in head neurons; pharyngeal muscle cell; tail neurons; uterine muscle; and ventral cord neurons. Is an ortholog of human RGS19 (regulator of G protein signaling 19).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
