FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Homozygotes for the rd1 mutation have severe retinal degeneration and vision loss. Rod cells are lost by 35 days of age; cone cells degenerate slower and some light sensitivity persists. Other allelic mutations produce similar or milder phenotypes. [provided by MGI curators]
