Photolysis of caged Ca2+ facilitates and inactivates but does not directly excite light-sensitive channels in Drosophila photoreceptors.

The Journal of neuroscience : the official journal of the Society for Neuroscience - 1 Jan 1995

Hardie R C

Abstract excerpt

Substantial evidence implicates the phosphoinositide cascade in invertebrate phototransduction, but the final pathway of excitation remains obscure. In order to test the hypothesis that Ca2+ is the excitatory messenger rapid concentration jumps of cytosolic Ca2+ were achieved in dissociated Drosophila photoreceptors by flash photolysis of the caged Ca2+ compounds DM-nitrophen and nitr-5. Both compounds were...
