RGS Family Protein

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** RGS family proteins activate GTPase and regulate G protein signaling by stimulating the inactivation of heterotrimeric G proteins. RGS family proteins are responsible for the rapid turnoff of G protein-coupled receptor signaling pathways. There are indications that a subset of RGS proteins regulate specific G protein-coupled receptor pathways.

**Synonyms:** - RGS Protein - Regulator of G-Protein Signaling Family Protein
