{"symbol":"GNAT2","synonyms":["ACHM4","GNATC"],"name":"guanine nucleotide binding protein (G protein), alpha transducing activity polypeptide 2","description":"Transducin is a 3-subunit guanine nucleotide-binding protein (G protein) which stimulates the coupling of rhodopsin and cGMP-phoshodiesterase during visual impulses. The transducin alpha subunits in rods and cones are encoded by separate genes. This gene encodes the alpha subunit in cones.
