Medical Definition of Transducin

1. 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. This entry appears with permission from the Dictionary of Cell and Molecular Biology (11 Mar 2008)
