| Background: | Visual signal transduction is mediated by a G-protein coupled cascade using cGMP as second messenger. This protein can be activated by cyclic GMP which leads to an opening of the cation channel and thereby causing a depolarization of rod photoreceptors. |
| Synonyms: | cGMP-gated cation channel alpha-1, Cyclic nucleotide-gated cation channel 1, Cyclic nucleotide-gated channel alpha-1, CNG channel alpha-1, CNG-1, CNG1, Cyclic nucleotide-gated channel, photoreceptor, Rod photoreceptor cGMP-gated channel subunit alpha, CNGA1, CNCG, CNCG1 |
| UniProt Protein Function: | Visual signal transduction is mediated by a G-protein coupled cascade using cGMP as second messenger. This protein can be activated by cyclic GMP which leads to an opening of the cation channel and thereby causing a depolarization of rod photoreceptors.CautionIt is uncertain whether Met-1 or Met-5 is the initiator. |

| NCBI Summary: | The protein encoded by this gene is involved in phototransduction. Along with another protein, the encoded protein forms a cGMP-gated cation channel in the plasma membrane, allowing depolarization of rod photoreceptors. This represents the last step in the phototransduction pathway. Defects in this gene are a cause of retinitis pigmentosa autosomal recessive (ARRP) disease. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2008] |
