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) is a Protein Coding gene. Diseases associated with PDE6A include Retinitis Pigmentosa 43 and Pde6a-Related Retinitis Pigmentosa. Among its related pathways are Metabolism of fat-soluble vitamins and Phototransduction. GO annotations related to this gene include 3,5-cyclic-nucleotide phosphodiesterase activity and 3,5-cyclic-GMP phosphodiesterase activity. An important paralog of this gene is PDE6B.

  • This protein participates in processes of transmission and amplification of the visual signal.

Tocris Summary for PDE6A Gene

  • Phosphodiesterases (PDEs) are a family of phosphohydrolyases that catalyze the hydrolysis of 3' cyclic phosphate bonds in adenosine and/or guanine 3',5' cyclic monophosphate (cAMP and/or cGMP). PDEs regulate the second messengers by controlling their degradation.

  • 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}.
