Summaries for PDE6A Gene

Entrez Gene Summary for PDE6A Gene

  • This gene encodes the cyclic-GMP (cGMP)-specific phosphodiesterase 6A alpha subunit, expressed in cells of the retinal rod outer segment. The phosphodiesterase 6 holoenzyme is a heterotrimer composed of an alpha, beta, and two gamma subunits. cGMP is an important regulator of rod cell membrane current, and its dynamic concentration is established by phosphodiesterase 6A cGMP hydrolysis and guanylate cyclase cGMP synthesis. The protein is a subunit of a key phototransduction enzyme and participates in processes of transmission and amplification of the visual signal. Mutations in this gene have been identified as one cause of autosomal recessive retinitis pigmentosa. [provided by RefSeq, Jul 2008]

GeneCards Summary for PDE6A Gene

PDE6A (Phosphodiesterase 6A, CGMP-Specific, Rod, Alpha) is a Protein Coding gene. Diseases associated with PDE6A include retinitis pigmentosa 43 and pde6a-related retinitis pigmentosa. Among its related pathways are Signaling by GPCR and Disease. GO annotations related to this gene include 3,5-cyclic-GMP phosphodiesterase activity. An important paralog of this gene is PDE2A.

Tocris Summary for PDE6A Gene

  • Phosphodiesterases (PDEs) are a family of related phosphohydrolyases that selectively catalyze the hydrolysis of 3' cyclic phosphate bonds in adenosine and/or guanine 3',5' cyclic monophosphate (cAMP and/or cGMP). They regulate the cellular levels, localization and duration of action of these second messengers by controlling the rate of their degradation. There are 11 subtypes of PDEs, named PDE1-11; PDE4, 7 and 8 selectively degrade cAMP, PDE5, 6 and 9 selectively degrade cGMP and PDE1, 2, 3, 10 and 11 degrade both cyclic nucleotides. PDEs are expressed ubiquitously, with each subtype having a specific tissue distribution. These enzymes are involved in many signal transduction pathways and their functions include vascular smooth muscle proliferation and contraction, cardiac contractility, platelet aggregation, hormone secretion, immune cell activation, and they are involved in learning and memory.

  • Retinitis pigmentosa 43 (RP43) [MIM:613810]: A retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. {ECO:0000269 PubMed:10393062, ECO:0000269 PubMed:7493036}. Note=The disease is caused by mutations affecting the gene represented in this entry.
