FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the beta subunit of a cyclic nucleotide-gated ion channel. The encoded beta subunit appears to play a role in modulation of channel function in cone photoreceptors. This heterotetrameric channel is necessary for sensory transduction, and mutations in this gene have been associated with achromatopsia 3, progressive cone dystrophy, and juvenile macular degeneration, also known as Stargardt Disease.

PHENOTYPE: Mice homozygous for a knock-out allele exhibit cone degeneration and decreased photopic response. [provided by MGI curators]
