CC   -!- FUNCTION: Inhibits signal transduction by increasing the GTPase
CC       activity of G protein alpha subunits thereby driving them into their
CC       inactive GDP-bound form. Binds to G(i) alpha-1, G(i) alpha-2, G(i)
CC       alpha-3 and G(q) alpha (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
