GNGT2

GNGT2, also known as Guanine nucleotide-binding protein G(t) subunit gamma-T2, is a protein that belongs to the family of guanine nucleotide-binding proteins (G proteins). GNGT2 is a subunit of the transducin complex, which plays a critical role in signal transduction in photoreceptor cells of the retina. One of the primary functions of GNGT2 is its involvement in the phototransduction cascade, a process by which light stimuli are converted into electrical signals that can be interpreted by the brain. In the retina, photoreceptor cells contain light-sensitive proteins called opsins, which undergo a conformational change upon absorbing photons. This change activates the associated...
