Previous Symbols for CNGA1 Gene
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]
GeneCards Summary for CNGA1 Gene
CNGA1 (Cyclic Nucleotide Gated Channel Alpha 1) is a Protein Coding gene. Diseases associated with CNGA1 include retinitis pigmentosa 49 and cnga1-related retinitis pigmentosa. Among its related pathways are Signaling by GPCR and Disease. GO annotations related to this gene include voltage-gated potassium channel activity and intracellular cAMP activated cation channel activity. An important paralog of this gene is KCNH1.
UniProtKB/Swiss-Prot for CNGA1 Gene
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
