A High-Throughput Drug Screening Strategy for Detecting Rhodopsin P23H Mutant Rescue and Degradation.

Invest. Ophthalmol. Vis. Sci. 56 , 2553-67, (2015)

Inherent instability of the P23H mutant opsin accounts for approximately 10% of autosomal dominant retinitis pigmentosa cases. Our purpose was to develop an overall set of reliable screening strategie...

Cubozoan genome illuminates functional diversification of opsins and photoreceptor evolution.

Sci. Rep. 5 , 11885, (2015)

Animals sense light primarily by an opsin-based photopigment present in a photoreceptor cell. Cnidaria are arguably the most basal phylum containing a well-developed visual system. The evolutionary hi...

Constitutive phospholipid scramblase activity of a G protein-coupled receptor.

Nat. Commun. 5 , 5115, (2014)

Opsin, the rhodopsin apoprotein, was recently shown to be an ATP-independent flippase (or scramblase) that equilibrates phospholipids across photoreceptor disc membranes in mammalian retina, a process...
