This review integrates recent structural and biochemical advances to explain how PINK1 activates Parkin and how PINK1/Parkin-mediated mitophagy is regulated and integrated with other cellular stress responses.
By defining molecular determinants and regulatory nodes in the PINK1/Parkin pathway, the paper highlights actionable targets and mechanisms for drug discovery, biomarker development, and therapies aimed at restoring mitochondrial quality control in Parkinson's disease.
