Functioni

Soluble retinoid carrier essential the proper function of both rod and cone photoreceptors. Participates in the regeneration of active 11-cis-retinol and 11-cis-retinaldehyde, from the inactive 11-trans products of the rhodopsin photocycle and in the de novo synthesis of these retinoids from 11-trans metabolic precursors. The cycling of retinoids between photoreceptor and adjacent pigment epithelium cells is known as the 'visual cycle'.1 Publication

Involvement in diseasei

Bothnia retinal dystrophy (BRD)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA type of retinitis punctata albescens. Affected individuals show night blindness from early childhood with features consistent with retinitis punctata albescens and macular degeneration.

Rod-cone dystrophy Newfoundland (NFRCD)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA rod-cone dystrophy reminiscent of retinitis punctata albescens but with a substantially lower age at onset and more-rapid and distinctive progression. Rod-cone dystrophies results from initial loss of rod photoreceptors, later followed by cone photoreceptors loss.
See also OMIM:607476
Retinitis punctata albescens (RPA)3 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of fleck retina disease characterized by aggregation of white flecks posteriorly in the retina, causing night blindness and delayed dark adaptation. It differs from fundus albipunctatus in being progressive and evolving to generalized atrophy of the retina.
