RGS19 Inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits thereby driving them into their inactive GDP-bound form. Binds to G-alpha subfamily 1 members, with the order G(i)a3 Highest expression in lung. Placenta, liver and heart also express high levels of GAIP.
