Summaries for PDE6B Gene

Entrez Gene Summary for PDE6B Gene

  • Photon absorption triggers a signaling cascade in rod photoreceptors that activates cGMP phosphodiesterase (PDE), resulting in the rapid hydrolysis of cGMP, closure of cGMP-gated cation channels, and hyperpolarization of the cell. PDE is a peripheral membrane heterotrimeric enzyme made up of alpha, beta, and gamma subunits. This gene encodes the beta subunit. Mutations in this gene result in retinitis pigmentosa and autosomal dominant congenital stationary night blindness. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2009]

GeneCards Summary for PDE6B Gene

PDE6B (Phosphodiesterase 6B) is a Protein Coding gene. Diseases associated with PDE6B include Night Blindness, Congenital Stationary, Autosomal Dominant 2 and Retinitis Pigmentosa-40. Among its related pathways are Phototransduction and Signaling by Wnt. 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 PDE6A.

UniProtKB/Swiss-Prot for PDE6B Gene

  • This protein participates in processes of transmission and amplification of the visual signal. Necessary for the formation of a functional phosphodiesterase holoenzyme.

Tocris Summary for PDE6B 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.

Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Retinitis pigmentosa 40 (RP40) [MIM:613801]: 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:22334370, ECO:0000269 PubMed:8394174, ECO:0000269 PubMed:8557257, ECO:0000269 PubMed:8595886, ECO:0000269 PubMed:8698075, ECO:0000269 PubMed:8956055, ECO:0000269 PubMed:9543643}.
