How do ALS-associated OPTN mutations mechanistically disrupt Rab8a binding and cellular function?

PARTIALLY ADDRESSED

The authors evaluate several ALS-associated mutations in OPTN's leucine-zipper domain but don't fully explain how these mutations mechanistically lead to disease pathogenesis. Understanding this link is critical for developing targeted ALS therapies. Gap type: unexplained_observation Source paper: Molecular Basis of the Recognition of the Active Rab8a by Optineurin.
