Predicted to enable G-protein alpha-subunit binding activity. Predicted to act upstream of or within negative regulation of signal transduction. Predicted to be located in brush border; clathrin-coated vesicle; and membrane raft. Is expressed in embryo; forelimb bud; palatal shelf epithelium; and primary palate epithelium. Orthologous to human RGS19 (regulator of G protein signaling 19). [provided by Alliance of Genome Resources, Apr 2022]
