G gamma 1, GNG1, GNGT1, Guanine nucleotide binding protein G, Transducin gamma chain, GBG1_HUMAN.
Heterotrimeric guanine nucleotide-binding proteins (G proteins) transduce extracellular signals received by transmembrane receptors to effector proteins. Transducin is a guanine nucleotide-binding protein found specifically in rod outer segments, where i
