Cyclic nucleotide-gated cation channel beta-1 (CNGB1)

Subunit of cyclic nucleotide-gated (CNG) stations, nonselective cation channels, which play important roles in both visual and olfactory signal transduction. When connected with CNGA1, it is involved in the regulation of ion flow into the rod photoreceptor outer segment (ROS), in response to light-induced alteration of the levels of intracellular cGMP.
