title: Calcium-binding proteins and nitric oxide in retinal function and disease.
abstract: Regulation of phototransduction in photoreceptor cells occurs via several feedback loops. Some of these circuits involve the neuron-specific Ca2+-binding proteins recoverin and guanylyl cyclase-activating protein. Recent findings suggest that these proteins are also involved in retinal diseases. Another Ca2+-regulated process in the retina is the synthesis of nitric oxide, a substance of potential neurotoxicity. This review discusses several Ca2+-mediated processes in the retina.
