    Age-related cataract is the leading cause of blindness globally, driven by lens protein aggregation.

  • 2

    Oxidative damage to tryptophan 163 in γS-crystallin destabilizes the protein and promotes cataract formation.

  • 3

    The study utilized genetic code expansion to introduce an oxidative mimic, allowing precise investigation of protein modifications.

  • 4

    The modified γS-crystallin showed reduced stability and increased aggregation tendency compared to the wild-type protein.

  • 5

    Findings may inform strategies to delay cataract formation through antioxidant therapies or stabilizing molecules.
