Family of cyclic nucleotide gated ion channels.
A variety of different cyclic nucleotide gated ion channels have recently been identified using molecular cloning and electrophysiological techniques. Current research is focussed on the specific molecular determinants that endow these channels with their distinctive character of gating, selectivity and modulation. In some cases, it has been possible to identify the specific physiological roles of different cyclic nucleotide gated channels. Their interactions with Ca2+ and calmodulin are particularly important, and determine the specific functions these channels subserve in distinct cells.
