1. A method for identifying a modulator of a cyclic nucleotide-gated (CNG) cation channel, the method comprising the steps of:
(i) contacting a compound with a polypeptide, the polypeptide (a) forming, with at least one CNG alpha subunit, a cation channel having the characteristic of cyclic nucleotide-gating; and (b) comprising the amino acid sequence of SEQ ID NO:1; and
(ii) determining the effect of the compound upon the cation channel, thereby identifying a modulator of the cation channel.
