RGS19

Regulator of G-protein signaling 19 is a protein that in humans is encoded by the RGS19 gene.

G proteins mediate a number of cellular processes. The protein encoded by this gene belongs to the RGS (regulators of G-protein signaling) family and specifically interacts with G protein, GAI3. This protein is a guanosine triphosphatase-activating protein that functions to down-regulate Galpha i/Galpha q-linked signaling.

Interactions
RGS19 has been shown to interact with GNAO1, GIPC1, OSTM1, GNAI1,  GNAI3   and GNAZ.
