RGS17 (Regulator Of G Protein Signaling 17): RGS17 is a gene that encodes a protein belonging to the regulator of G protein signaling (RGS) family. These proteins assist in controlling G protein-coupled receptor (GPCR) signalling by accelerating the conversion of GTP to GDP. RGS17 may affect multiple GPCR-regulated pathways, influencing various physiological processes.
