Wild-type opsin mainly formed oligomers. Only a minor population formed aggregates. The G188R opsin mutant mainly formed aggregates. When wild-type opsin and G188R opsin were coexpressed in cells, properly folded wild-type opsin did not aggregate with G188R opsin and was trafficked normally to the cell membrane. The autosomal dominant phenotype due to misfolded opsin mutants is not due to WT-mutant physical interaction.

Retinitis pigmentosa is an inherited progressive disease which is a major cause of blindness in western communities. It can be inherited as an autosomal dominant, autosomal recessive, or X-linked recessive disorder. In the autosomal dominant form,which comprises about 25% of total cases, approximately 30% of families have mutations in the gene encoding the rod photoreceptor-specific protein rhodopsin. This is the transmembrane protein which, when photoexcited, initiates the visual transduction cascade. Defects in this gene are also one of the causes of congenital stationary night blindness.
