Parkin function
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). Web11 Jun 2024 · Parkin was described as a molecular factor that plays a fundamental role in mitochondrial dynamics, which is regulated by the interaction between Parkin and PINK1, a serine/threonine kinase, whose mutations are also involved in the development of PD ( Geisler et al., 2010 ).
