DiseaseCone-rod dystrophy 6 (CORD6) [MIM:601777]: An inherited retinal dystrophy characterized by retinal pigment deposits visible on fundus examination, predominantly in the macular region, and initial loss of cone photoreceptors followed by rod degeneration. This leads to decreased visual acuity and sensitivity in the central visual field, followed by loss of peripheral vision. Severe loss of vision occurs earlier than in retinitis pigmentosa. {ECO:0000269|PubMed:12552567, ECO:0000269|PubMed:15111605, ECO:0000269|PubMed:18332321, ECO:0000269|PubMed:18487367, ECO:0000269|PubMed:20517349, ECO:0000269|PubMed:21552474, ECO:0000269|PubMed:22194653, ECO:0000269|PubMed:23734073, ECO:0000269|PubMed:24480840, ECO:0000269|PubMed:9618177, ECO:0000269|PubMed:9683616}. Note=The disease is caused by mutations affecting the gene represented in this entry.
DiseaseLeber congenital amaurosis 1 (LCA1) [MIM:204000]: A severe dystrophy of the retina, typically becoming evident in the first years of life. Visual function is usually poor and often accompanied by nystagmus, sluggish or near-absent pupillary responses, photophobia, high hyperopia and keratoconus. {ECO:0000269|PubMed:11035546, ECO:0000269|PubMed:12365911, ECO:0000269|PubMed:17724218, ECO:0000269|PubMed:21602930, ECO:0000269|PubMed:8944027}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Enzyme RegulationActivated by GCAP-1; inhibited by calcium.
FunctionProbably plays a specific functional role in the rods and/or cones of photoreceptors. It may be the enzyme involved in the resynthesis of cGMP required for recovery of the dark state after phototransduction.
SimilarityBelongs to the adenylyl cyclase class-4/guanylyl cyclase family. {ECO:0000255|PROSITE-ProRule:PRU00099}.
SimilarityContains 1 guanylate cyclase domain. {ECO:0000255|PROSITE-ProRule:PRU00099}.
SimilarityContains 1 protein kinase domain. {ECO:0000255|PROSITE-ProRule:PRU00159}.
Subcellular LocationMembrane; Single-pass type I membrane protein.
Tissue SpecificityRetina. Localized exclusively in the nuclei and inner segments of the rod and cone photoreceptor cells.
