The formation of stable rhodopsin-arrestin complexes induces apoptosis and photoreceptor cell degeneration.

Abstract excerpt

Although many different mutations in humans and Drosophila cause retinal degeneration, in most cases, a molecular mechanism for the degeneration has not been found. We now demonstrate the existence of stable, persistent complexes between rhodopsin and its regulatory protein arrestin in several different retinal degeneration mutants. Elimination of these rhodopsin-arrestin complexes by removing either rhodopsin or...
