USP13 deubiquitinates and stabilizes PINK1 and Parkin, enhancing mitophagy. USP13 downregulation in sporadic PD brains leads to damaged mitochondrial accumulation. USP13 restoration may enhance mitophagy and protect dopaminergic neurons, though no tool compounds exist and mechanism validation is incomplete.
LRRK2 G2019S mutation hyperactivates kinase activity, causing excessive phosphorylation of Rab GTPases (Rab8A, Rab10, Rab12), impairing endosomal trafficking and lysosomal degradation of α-synuclein. Selective LRRK2 inhibitors restore lysosomal function and reduce pathological α-synuclein accumulation.
