WebParkin is an E3-ubiquitin ligase belonging to the RBR (RING – In Between RING – RING) family. Mutations in Parkin that result in a loss-of-function are the most frequent cause of familial Parkinson’s disease and are responsible for a large percentage of autosomal recessive juvenile parkinsonism (AR-JP). Parkin plays a crucial role in mitophagy and clearance of reactive oxygen species. Mitophagy is the elimination of damaged mitochondria in autophagosomes, and is dependent on a positive feedback cycle involving synergistic action of parkin and PINK1. Following severe cellular insult, rundown of mitochondrial membrane potential prevents import of PINK1 into the mitochondrial matrix and causes it to aggregate on the outer mitochondrial membrane (OMM). Parkin is recruit…
