Rod photoreceptor cyclic GMP gated-channel protein is a key component of the visual transduction cascade in the vertebrate retina. The protein is composed of at least two subunits (α and β). Mutations in the α-subunit (CNGC1) have been shown to cause retinitis pigmentosa (RP) in humans. Several heterogeneous canine retinal diseases, which are clinically similar to RP, are known collectively as progressive retinal atrophy (PRA) and occur in dogs in a breed-specific manner. For the purpose of examining CNGC1 gene as a candidate for PRA, we report here the characterization of canine CNGC1 cDNA, and examine the expression of the …
