Entrez ID 2776
Gene name G protein subunit alpha q
Gene symbol GNAQ
Synonyms (NCBI Gene)
CMALCMC1G-ALPHA-qGAQSWS
Chromosome 9
Chromosome location 9q21.2
Summary 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
