Abstract:
Parkinson disease (PD) is a neurodegenerative disease characterized by the loss of dopaminergic neurons in the substantia nigra, primarily due to mitochondria dysfunction. PRKN (parkin RBR E3 ubiquitin protein ligase) and PINK1 (PTEN induced kinase 1) are linked to early-onset cases of PD and essential for the clearance of damaged mitochondria via selective mitochondrial autophagy (mitophagy). In a recent publication, we detail how a small molecule can activate PRKN mutants that are unable to be phosphorylated, restoring mitophagy in cellular assays. These findings offer hope for the design of therapeutic drugs for some forms of PD.
