Enzyme Processing Critical for Color Vision Protein Function, Study Reveals

Scientists have identified a crucial enzyme process that maintains color vision protein stability. Research indicates this mechanism specifically affects cone photoreceptor function while sparing rod cells.

Breakthrough in Vision Science

Researchers have uncovered a critical mechanism governing color vision protein function, according to a recent study published in Scientific Reports. The investigation reveals that postprenylation processing, mediated by the RCE1 enzyme, is specifically required for maintaining cone photoreceptor phosphodiesterase 6 (PDE6) localization and stability. Sources indicate this discovery explains previously unknown mechanisms behind cone-specific vision deficiencies.
