Retinal pigment epithelium-specific 65 kDa protein is a protein that in humans is encoded by the RPE65 gene.[1][2]


The retinal pigment epithelium-specific 65 kDa protein is located in the retinal pigment epithelium and is involved in the conversion of all-trans retinol to 11-cis retinal during phototransduction, which is then used in visual pigment regeneration in photoreceptor cells.

Clinical significance[edit]

Mutations in this gene have been associated with Leber's congenital amaurosis type 2 (LCA2) and retinitis pigmentosa.[2][3]
