Summary: Enables cyclic nucleotide-activated monoatomic ion channel activity. Acts upstream of or within several processes, including photoreceptor cell maintenance; photoreceptor cell outer segment organization; and sensory perception of smell. Located in membrane and photoreceptor outer segment. Is expressed in several structures, including head mesenchyme; incisor; limb; sensory organ; and skeleton. Used to study retinitis pigmentosa. Human ortholog(s) of this gene implicated in retinitis pigmentosa and retinitis pigmentosa 45. Orthologous to human CNGB1 (cyclic nucleotide gated channel subunit beta 1).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
