Regulator of G-Protein Signaling 19

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

**Definition:** Regulator of G-protein signaling 19 (217 aa, ~25 kDa) is encoded by the human RGS19 gene. This protein plays a role in the inhibition of signal transduction by increasing the GTPase activity of G-protein alpha subunits.

**Synonyms:** - G Alpha Interacting Protein - G Protein Signaling Regulator 19 - G-Alpha Interacting Protein - GAIP - GAIP Protein - Guanine Nucleotide Binding Protein Alpha Inhibiting Activity Polypeptide 3 Interacting Protein - RGS19
