Description

The study shows PRKN specifically accelerates RHOT1 turnover, disrupting mitochondrial transport, but doesn’t explain why RHOT1 is preferentially targeted. Understanding this selectivity mechanism is crucial for developing targeted interventions that preserve mitochondrial transport while maintaining quality control.
