GNAQ Antibody – Polyclonal

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.[provided by RefSeq, Nov 2010]

G-alpha(q): a guanine nucleotide-binding protein of the G12 class of G-alpha proteins. Agonist binding to Gq-coupled receptors may block Akt activation via the release of active G-alpha(q) subunits that inhibit phosphatidylinositol 3-kinase. Heterotrimeric G proteins are composed of 3 units; alpha, beta and gamma. The alpha chain contains the guanine nucleotide binding site.
