The precise function of this gene is unknown, however, the encoded protein is a component of a multiprotein E3 ubiquitin ligase complex that mediates the targeting of substrate proteins for proteasomal degradation. Mutations in this gene are known to cause Parkinson disease and autosomal recessive juvenile Parkinson disease. Alternative splicing of this gene produces multiple transcript variants encoding distinct isoforms. Additional splice variants of this gene have been described but currently lack transcript support.,PRKN,AR-JP,LPRS2,PARK2,PDJ,Parkin,Signal Transduction,Kinase,Tyrosine kinases,ErbB-HER Signaling Pathway,Cell Biology & Developmental Biology,Autophagy,Ubiquitin,Ubiquitin-Proteasome Signaling Pathway,Endocrine & Metabolism,Mitochondrial metabolism,Mitophagy fission and fusion,Insulin Receptor Signaling Pathway,Immunology & Inflammation,B Cell Receptor Signaling Pathway,IL-6 Receptor Signaling Pathway,Neuroscience,Neurodegenerative Diseases,Dopamine Signaling in Parkinson's Disease,Neurodegenerative Diseases Markers,Mitochondrial Control of Autophagy,PRKN
