CC -!- FUNCTION: Guanine nucleotide-binding proteins (G proteins) are involved
CC as modulators or transducers in various transmembrane signaling
CC systems. {ECO:0000250|UniProtKB:P50148}.
CC -!- SUBUNIT: G proteins are composed of 3 units; alpha, beta and gamma. The
CC alpha chain contains the guanine nucleotide binding site.
CC {ECO:0000250|UniProtKB:P50148}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P50148};
CC Lipid-anchor {ECO:0000250|UniProtKB:P50148}. Golgi apparatus
CC {ECO:0000250|UniProtKB:P50148}. Nucleus {ECO:0000250|UniProtKB:P21279}.
CC Nucleus membrane {ECO:0000250|UniProtKB:P21279}.
CC -!- PTM: Palmitoylated. Palmitoylation occurs in the Golgi and participates
CC in the localization of GNAQ to the plasma membrane.
CC {ECO:0000250|UniProtKB:P21279}.
CC -!- SIMILARITY: Belongs to the G-alpha family. G(q) subfamily.
CC {ECO:0000305}.
