Description

The study demonstrates pathologic α-synuclein accumulation in ER and mitochondria following DNAJC6 paucity, but doesn’t explain the organelle-specific targeting mechanism. This subcellular specificity may be key to understanding PARK19 pathogenesis and developing compartment-targeted interventions.
