Summaries for GUCA1A Gene

Entrez Gene Summary for GUCA1A Gene

  • This gene encodes an enzyme that plays a role in the recovery of retinal photoreceptors from photobleaching. This enzyme promotes the activity of retinal guanylyl cyclase-1 (GC1) at low calcium concentrations and inhibits GC1 at high calcium concentrations. Mutations in this gene can cause cone dystrophy 3 and code-rod dystrophy 14. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

GeneCards Summary for GUCA1A Gene

GUCA1A (Guanylate Cyclase Activator 1A) is a Protein Coding gene. Diseases associated with GUCA1A include Cone Dystrophy 3 and Choroidal Dystrophy, Central Areolar, 1. Among its related pathways are Phototransduction and MicroRNAs in cardiomyocyte hypertrophy. Gene Ontology (GO) annotations related to this gene include calcium ion binding and guanylate cyclase regulator activity. An important paralog of this gene is GUCA1C.

UniProtKB/Swiss-Prot for GUCA1A Gene

  • Stimulates retinal guanylyl cyclase when free calcium ions concentration is low and inhibits guanylyl cyclase when free calcium ions concentration is elevated (PubMed:19459154). This Ca(2+)-sensitive regulation of retinal guanylyl cyclase is a key event in recovery of the dark state of rod photoreceptors following light exposure.

  • 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:0000269 PubMed:11108966, ECO:0000269 PubMed:11146732, ECO:0000269 PubMed:11484154, ECO:0000269 PubMed:15505030, ECO:0000269 PubMed:15735604, ECO:0000269 PubMed:15790869, ECO:0000269 PubMed:19459154, ECO:0000269 PubMed:9425234}.
