[Calcium-dependent interaction of transducin with calmodulin-sepharose].
It has been shown by affinity chromatography on calmodulin-sepharose that transducin, a G protein of bovine retinal rod outer segments interacts with Ca(2+)-calmodulin. This result assumes that the main part of calmodulin in dark retinal rod outer segments is associated with transducin. It has been suggested that photoactivation of retinal rods induces changes in intracellular calmodulin concentration, which may be one of the steps involved in the light adaptation of photoreceptor.
