Transducin protein beta-gamma complex. Molecular model of the beta-gamma dimer of the heterotrimeric G protein transducin. This complex consists of two of the protein's three subunits, the beta subunit and the gamma subunit. Transducin is one of the key proteins in the retina, forming part of visual phototransduction, where light hitting the retina is converted to electrical signals.
