Transducin mediates signal transduction in a classical G protein-coupled receptor (GPCR) phototransduction cascade. Interactions of transducin with the receptor and the effector molecules had been ext
Rhodopsin kinase (RK) catalyzes the phosphorylation of rhodopsin (Rho) as one of the steps in quenching photoactivated Rho. In this work, we investigated the autophosphorylation of RK and how it affec
cAMP plays a dual role in olfaction. It serves as the excitatory second messenger in signal transduction, but is also required to establish correct axonal targeting to glomeruli in the olfactory bulb.
