WebAug 14, 2008 · Arrestins are proteins that arrest the activity of G protein-coupled receptors (GPCRs). While it is well established that normal inactivation of photoexcited rhodopsin, the GPCR of rod phototransduction, requires arrestin (Arr1), it has been controversial whether the same requirement holds for cone opsin inactivation. Mouse cone photoreceptors … WebPhototransduction is the process by which this singular event is sufficiently amplified to create an electrical signal that can reliably be detected by the rest of the visual system. …
