Cyclic nucleotide-gated channel alpha 3

Cyclic nucleotide-gated channel alpha 3 (CNGA3) is a protein that forms a part of the ion channel complex involved in sensory transduction, particularly in photoreceptors in the retina. It is one of the alpha subunits of the cyclic nucleotide-gated (CNG) channels, which are sensitive to cyclic nucleotides such as cyclic AMP (cAMP) and cyclic GMP (cGMP).
