The protein then changes to metarhodopsin II and sticks to another protein, called transducin
Phosducin, a light-regulated phosphoprotein, binds to subunits of transducin, a transducer G protein (Lee et al.
Phosducin is a light-regulated phosphoprotein which binds to subunits of transducin (Lee et al.
Activation of pertussis toxin sensitive G-protein in membranes of SH-SY5Y human neuroblastoma cells and bovine transducin
A photon hitting a single rhodopsin molecule might activate hundreds of transducin molecules.
More than a decade ago, several research groups reported that transducin moves away from the outer, photon-sensing segments of rods when rodent eyes were exposed to light.
Specifically, PDC modulates visual phototransduction by binding with the [beta]- and [gamma]-subunits of the heterotrimeric G-protein (G[beta][gamma]) transducin (Kuo et al.
Furthermore, it is involved in the regulation of the light-dependent movement of the photoreceptor G-protein transducin (Schulz, 2001; Lukov et al.
Intrinsic biophysical monitors of transducin
activation: UV-visible spectroscopy, light scattering and evanescent field techniques.
He goes on to describe the next two proteins in the bitter pathway, the G-protein transducin
and a taste specific phosphodiesterase that is activated by transducin

The researchers were surprised at how much this new molecule looks like the transducins
