Diverse effects of pathogenic mutations of Parkin that catalyze multiple monoubiquitylation in vitro.

Abstract excerpt

Mutational dysfunction of PARKIN gene, which encodes a double RING finger protein and has ubiquitin ligase E3 activity, is the major cause of autosomal recessive juvenile Parkinsonism. Although many studies explored the functions of Parkin, its biochemical character is poorly understood. To address this issue, we established an E3 assay system using maltose-binding protein-fused Parkin purified from Escherichia...
