View Full Version : Do cGMP-gated Na+ channels occur ahywhere that is not in the retina?

I have to write a paper about cGMP-gated Na+ channels that occur in the body and not the retina, and compare these systems to the cGMP process in the eye (which is unique since it hyperpolarizes the rods in the presence of light). The issue I'm having with this topic is that I cannot seem to find cGMP Na+ channels that are not in the retina. All the papers I've read about cGMP-gated ion channles almost exclusively deal with Ca2+ ions, rather than Na+ ions.

I think that the fact that all the other cGMP-channels in the body deal with Ca+ rather than Na+ is important to the topic, but I'm not quite sure why. Any help on the topic is greatly appreciated! :mrgreen:

Edit: Screwed up the title :(
