Abstract

Molday and Hsu review results from in vitro experiments, which indicate that Ca-bound calmodulin reduces the cGMP sensitivity of the cyclic nucleotide-gated channel of photoreceptor cells, and speculate about the role they might play in the recovery of the light response. We discuss results from in vivo experiments that argue against the participation of Ca-calmodulin in photorecovery.
