Pathogenic mutations cause rhodopsin to misfold and disrupt its function. In this study, a yeast-based assay was used to screen for compounds that have the potential to rescue the function of mutant rhodopsin. It was confirmed that 9-cis retinal could partially rescue light-dependent activation of disease-associated rhodopsin mutation (P23H). A phenotypic screen was also done with yeast assays to screen compounds from the LOPAC1280 library and a peptidomimetic library.
