RPE65 

Retinal pigment epithelium 65 kDa protein

RPE65 (Retinal pigment epithelium 65 kDa protein) is a critical enzyme in the visual cycle that is specifically expressed in retinal pigment epithelial (RPE) cells. As a retinoid isomerohydrolase, RPE65 catalyzes the conversion of all-trans-retinyl esters to 11-cis-retinol, a vital process for visual phototransduction [1].RPE65 facilitates retinoid isomerization through its iron-binding site, maintaining the continuous supply of 11-cis-retinal in the retina - the essential precursor for rhodopsin regeneration [2]. Deficiencies in RPE65 function disrupt the visual cycle and are associated with various inherited retinal disorders, including Leber congenital amaurosis type 2 (LCA2) and retinitis pigmentosa [3].
