Introduction: G-Protein Signaling in the Retina,l surface receptors for sensing molecules or physical stimuli and the intracellular machinery for converting their presence into changes in biochemical activity that allows the organism to exploit this information.

G-Protein–Effector Coupling in the Vertebrate Phototransduction Cascadeto its classical effector phosphodiesterase 6. A new level of mechanistic insight has been achieved from the atomic structures of the signaling molecules. Recent studies on light-dependent translocation of transducin in rods raise a possibility for noncanonical transducin signaling and partners in the photoreceptor synaptic terminal.

G Protein Deactivation Mechanisms in Vertebrate Phototransductioncidate which, when, where, and how each component is used. The field of phototransduction has historically provided unrivaled details in describing general principles of G-protein signaling. This chapter intends to cover the reactions that dominate the rate of phototransduction recovery in rod and cone photoreceptors.
