Protein Structure
UniProt Annotation
Function Stimulates guanylyl cyclase 1 (GC1) when free calcium ions concentration is low and inhibits GC1 when free calcium ions concentration is elevated. This Ca(2+)-sensitive regulation of GC is a key event in recovery of the dark state of rod photoreceptors following light exposure.
Subcellular Localization Membrane; Lipid-anchor.
Disease Associations Cone dystrophy 3 (COD3) [MIM:602093]: An autosomal dominant cone dystrophy. Cone dystrophies are retinal dystrophies characterized by progressive degeneration of the cone photoreceptors with preservation of rod function, as indicated by electroretinogram. However, some rod involvement may be present in some cone dystrophies, particularly at late stage. Affected individuals suffer from photophobia, loss of visual acuity, color vision and central visual field. Another sign is the absence of macular lesions for many years. Cone dystrophies are distinguished from the cone-rod dystrophies in which some loss of peripheral vision also occurs. {ECO:0000269PubMed:11146732, ECO:0000269PubMed:11484154, ECO:0000269PubMed:15505030, ECO:0000269PubMed:15735604, ECO:0000269PubMed:15790869, ECO:0000269PubMed:19459154, ECO:0000269PubMed:9425234}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Retina; cone outer and inner segments, in particular, in disk membrane regions, and to a lesser extent rod inner and outer segments.
