Retinal pigment epithelium 65 (RPE65) also known as retinoid isomerohydrolase is a 65 kDa enzyme located within the human retinal pigment epithelium cells. PRE65 is responsible for the chemical conversion of ''all-trans''-retinyl ester to ''11-cis''-retinol in the visual cycle.

(''R'')-emixustat (ACU-4429) is an investigational small molecule inhibitor of RPE65 first invented by a British-American chemist, Ian L. Scott. Formulated as an hydrochloride salt, (''R'')-emixustat hydrochloride is taken by mouth and functions as a visual cycle modulator (VCM) to reduce toxic retinal byproducts such as A2E.

-
In 2008, Acucela Inc. partnered with Otsuka Pharmaceutical Company for the continued development of (''R'')-emixustat as a potential inhibitor of RPE65. Currently (''R'')-emixustat is in Phase III clinical trials in the United States for the potential treatment of Stargard's disease, a juvenile form of atrophic (dry) age dependent macular degeneration (AMD). Additionally, (''R'')-emixustat is investigated as potential therapy for diabetic retinopathy and diabetic macular edema.

This is a sample scene created with SAT to <scene name="/12/3456/Sample/1">color</scene> by Group, and another to make <scene name="/12/3456/Sample/2">a transparent representation</scene> of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
