Summaries for GUCY2D Gene

Entrez Gene Summary for GUCY2D Gene

  • This gene encodes a retina-specific guanylate cyclase, which is a member of the membrane guanylyl cyclase family. Like other membrane guanylyl cyclases, this enzyme has a hydrophobic amino-terminal signal sequence followed by a large extracellular domain, a single membrane spanning domain, a kinase homology domain, and a guanylyl cyclase catalytic domain. In contrast to other membrane guanylyl cyclases, this enzyme is not activated by natriuretic peptides. Mutations in this gene result in Leber congenital amaurosis and cone-rod dystrophy-6 diseases. [provided by RefSeq, Dec 2008]

GeneCards Summary for GUCY2D Gene

GUCY2D (Guanylate Cyclase 2D, Retinal) is a Protein Coding gene. Diseases associated with GUCY2D include Cone-Rod Dystrophy 6 and Leber Congenital Amaurosis 1. Among its related pathways are CREB Pathway and Phototransduction. GO annotations related to this gene include transferase activity, transferring phosphorus-containing groups and protein tyrosine kinase activity. An important paralog of this gene is GUCY1A3.

UniProtKB/Swiss-Prot for GUCY2D Gene

  • Probably 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.

  • Cone-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}.
