CC -!- FUNCTION: Guanine nucleotide-binding proteins (G proteins) are involved
CC as modulators or transducers in various transmembrane signaling
CC systems. Required for platelet activation. Regulates B-cell selection
CC and survival and is required to prevent B-cell-dependent autoimmunity.
CC Regulates chemotaxis of BM-derived neutrophils and dendritic cells (in
CC vitro) (By similarity). Transduces FFAR4 signaling in response to long-
CC chain fatty acids (LCFAs) (By similarity). Together with GNA11,
CC required for heart development (By similarity).
CC {ECO:0000250|UniProtKB:P21279, 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. Binds NHERF1.
CC Forms a complex with PECAM1 and BDKRB2. Interacts with PECAM1 (By
CC similarity). Interacts with GAS2L2 (By similarity). {ECO:0000250,
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}. Note=Colocalizes with
CC the adrenergic receptors, ADREN1A and ADREN1B, at the nuclear membrane
CC of cardiac myocytes. {ECO:0000250|UniProtKB:P21279}.
CC -!- PTM: Palmitoylated by ZDHHC3 and ZDHHC7. Palmitoylation occurs in the
CC Golgi and participates in the localization of GNAQ to the plasma
CC membrane. {ECO:0000250|UniProtKB:P21279}.
CC -!- PTM: Histaminylated at Gln-209 residues by TGM2.
CC {ECO:0000250|UniProtKB:P21279}.
CC -!- SIMILARITY: Belongs to the G-alpha family. G(q) subfamily.
CC {ECO:0000305}.
