Deactivation Mechanisms of Rod Phototransduction (The Cogan Lecture)

submitted by: arvojenny
The absorption of photons in rods and cones of the retina activate homologous biochemical signaling cascades that lead to the electrical changes that subserve the first steps in vision. Persistent activity of the cascade interferes with the ability of the photoreceptor to signal the absorption of subsequent photons, ultimately limiting the photoreceptor’s sensitivity and temporal resolution. This article summarizes recent work on transgenic and knockout mouse rods that have revealed the...
