Genetic forms of PD are associated with variants in FBXO7 and PI31. Combining biochemical and structural approaches, we describe the proteasome interaction of these proteins and map disease variants to disruption of proteasome interaction.
Cryo-ET showed protein aggregates, altered cristae, and reduced ribosome complexes in stressed mitochondria. Mitochondrial Hsp60 undergoes conformational changes to aid in protein folding, shedding light on mitochondrial proteostasis mechanisms.
A HeLa cell line expressing PINK1 fused to GFP from the endogenous locus was generated using CRISPR–Cas9 nickase–mediated genome editing with homology-directed repair. GFP-positive clones were isolated by fluorescence-activated cell sorting.
