GNAQ
geneOn this page
Also known as G-ALPHA-qGAQ
Summary
GNAQ (G protein subunit alpha q, HGNC:4390) is a protein-coding gene on chromosome 9q21.2, encoding Guanine nucleotide-binding protein G(q) subunit alpha (P50148). Guanine nucleotide-binding proteins (G proteins) function as transducers downstream of G protein-coupled receptors (GPCRs) in numerous signaling cascades. In precision oncology, GNAQ Mutation confers sensitivity to Trametinib in Uveal Melanoma (CIViC Level B); 7 further curated variant–drug associations are listed below. It is a selective cancer dependency (DepMap: 13.4% of cell lines).
This locus encodes a guanine nucleotide-binding protein. The encoded protein, an alpha subunit in the Gq class, couples a seven-transmembrane domain receptor to activation of phospolipase C-beta. Mutations at this locus have been associated with problems in platelet activation and aggregation. A related pseudogene exists on chromosome 2.

Function. Guanine nucleotide-binding proteins (G proteins) function as transducers downstream of G protein-coupled receptors (GPCRs) in numerous signaling cascades. The alpha chain contains the guanine nucleotide binding site and alternates between an active, GTP-bound state and an inactive, GDP-bound state. Signaling by an activated GPCR promotes GDP release and GTP binding. The alpha subunit has a low GTPase activity that converts bound GTP to GDP, thereby terminating the signal. Both GDP release and GTP hydrolysis are modulated by numerous regulatory proteins. Signaling is mediated via phospholipase C-beta-dependent inositol lipid hydrolysis for signal propagation: activates phospholipase C-beta: following GPCR activation, GNAQ activates PLC-beta (PLCB1, PLCB2, PLCB3 or PLCB4), leading to production of diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3). Required for platelet activation. Regulates B-cell selection and survival and is required to prevent B-cell-dependent autoimmunity. Regulates chemotaxis of BM-derived neutrophils and dendritic cells (in vitro). Transduces FFAR4 signaling in response to long-chain fatty acids (LCFAs). Together with GNA11, required for heart development.
Subunit / interactions. G proteins are composed of 3 units; alpha, beta and gamma. The alpha chain contains the guanine nucleotide binding site. Interacts (GDP-bound form) with RIC8A (via C-terminus); promoting GNAQ folding and association with the plasma membrane. Binds NHERF1. Forms a complex with PECAM1 and BDKRB2. Interacts with GAS2L2. Interacts with CCKBR.
Subcellular location. Cell membrane. Golgi apparatus. Nucleus. Nucleus membrane.
Tissue specificity. Predominantly expressed in ovary, prostate, testis and colon. Down-regulated in the peripheral blood lymphocytes (PBLs) of rheumatoid arthritis patients (at protein level).
Post-translational modifications. Palmitoylated by ZDHHC3 and ZDHHC7. Palmitoylation occurs in the Golgi and participates in the localization of GNAQ to the plasma membrane. (Microbial infection) Deamidated at Gln-209 by Photorhabdus asymbiotica toxin PAU_02230, blocking GTP hydrolysis of heterotrimeric GNAQ or GNA11 and G-alphai (GNAI1, GNAI2 or GNAI3) proteins, thereby activating RhoA. Histaminylated at Gln-209 residues by TGM2.
Disease relevance. Capillary malformations, congenital (CMC) [MIM:163000] A form of vascular malformations that are present from birth, tend to grow with the individual, do not regress spontaneously, and show normal rates of endothelial cell turnover. Capillary malformations are distinct from capillary hemangiomas, which are highly proliferative lesions that appear shortly after birth and show rapid growth, slow involution, and endothelial hypercellularity. The disease is caused by variants affecting the gene represented in this entry. Sturge-Weber syndrome (SWS) [MIM:185300] A syndrome characterized by an intracranial vascular anomaly, leptomeningeal angiomatosis, most often involving the occipital and posterior parietal lobes. The most common features are facial cutaneous vascular malformations (port-wine stains), seizures, and glaucoma. Stasis results in ischemia underlying the leptomeningeal angiomatosis, leading to calcification and laminar cortical necrosis. The clinical course is highly variable and some children experience intractable seizures, intellectual disability, and recurrent stroke-like episodes. The disease is caused by variants affecting the gene represented in this entry.
Similarity. Belongs to the G-alpha family. G(q) subfamily.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 144 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
