| transducin | <protein> A GTP-binding protein found in the disc membrane of retinal rods and cones: of the part of the cascade involved in transduction of light to a nervous impulse. A complex of three subunits, alpha (39 kD), beta (36 kD) and gamma (8 kD). Photoexcited rhodopsin interacts with transducin and promotes the exchange of GTP for GDP on the _ subunit. The GTP _ subunit dissociates from the complex and activates a cGMP phospodiesterase by removing an inhibitory subunit. The _ subunit of transducin can be ADP ribosylated by cholera toxin and pertussis toxin. (18 Nov 1997) |

| transducin |
a G protein of the disk membrane of the retinal rods that interacts with activated rhodopsin and participates in the triggering of a nerve impulse in vision; it stimulates hydrolysis of cyclic guanosine monophosphate, beginning the cascade that closes specific ion channels and generates an action potential.
