Guanine nucleotide-binding protein G(q) subunit alpha is a protein that in humans is encoded by the GNAQ gene. Together with GNA11 (its paralogue), it functions as a Gq alpha subunit.


- mutated in melanocytic tumors

- Mosaic activating mutations in GNA11 and GNAQ are associated with phakomatosis pigmentovascularis and extensive dermal melanocytosis. (26778290)
