The native rat olfactory cyclic nucleotide-gated channel is composed of three distinct subunits.

Abstract

Cyclic nucleotide-gated (CNG) channels play central roles in visual and olfactory signal transduction. In the retina, rod photoreceptors express the subunits CNCalpha1 and CNCbeta1a. In cone photoreceptors, only CNCalpha2 expression has been demonstrated so far. Rat olfactory sensory neurons (OSNs) express two homologous subunits, here designated CNCalpha3… (More)
