Guanine nucleotide-binding protein G(T) subunit gamma-T1 is a protein that in humans is encoded by the GNGT1 gene.^[5]^[6] Either GNGT1 or GNGT2 is the gamma subunit (G_γ) of the G_βγ part of transducin (written G(T) or G_t), a heterotrimeric G-protein naturally expressed in vertebrate retina rod and cone cells. GNGT1 only occurs in rod cells, and GNGT2 only occurs in cone cells, with a different alpha (G_α) subunit.^[7]^[8]
