== Disease ==
[https://www.uniprot.org/uniprot/PRKN_HUMAN PRKN_HUMAN] Young adult-onset Parkinsonism. Disease susceptibility may be associated with variations affecting the gene represented in this entry. Heterozygous mutations act as susceptibility alleles for late-onset Parkinson disease (PubMed:12730996 and PubMed:12629236).  The disease is caused by mutations affecting the gene represented in this entry.  Defects in PRKN may be involved in the development and/or progression of ovarian cancer.
== Function ==
[https://www.uniprot.org/uniprot/PRKN_HUMAN PRKN_HUMAN] Functions within a multiprotein E3 ubiquitin ligase complex, catalyzing the covalent attachment of ubiquitin moieties onto substrate proteins, such as BCL2, SYT11, CCNE1, GPR37, RHOT1/MIRO1, MFN1, MFN2, STUB1, SNCAIP, SEPT5, TOMM20, USP30, ZNF746 and AIMP2 (PubMed:10973942, PubMed:10888878, PubMed:11431533, PubMed:12150907, PubMed:12628165, PubMed:16135753, PubMed:21376232, PubMed:23754282, PubMed:23620051, PubMed:24660806, PubMed:24751536). Mediates monoubiquitination as well as 'Lys-6', 'Lys-11', 'Lys-48'-linked and 'Lys-63'-linked polyubiquitination of substrates depending on the context (PubMed:19229105, PubMed:20889974, PubMed:25621951). Participates in the removal and/or detoxification of abnormally folded or damaged protein by mediating 'Lys-63'-linked polyubiquitination of misfolded proteins such as PARK7: 'Lys-63'-linked polyubiquitinated misfolded proteins are then recognized by HDAC6, leading to their recruitment to aggresomes, followed by degradation (PubMed:17846173, PubMed:19229105). Mediates 'Lys-63'-linked polyubiquitination of a 22 kDa O-linked glycosylated isoform of SNCAIP, possibly playing a role in Lewy-body formation (PubMed:11590439, PubMed:11431533, PubMed:19229105, PubMed:11590439, PubMed:15728840). Mediates monoubiquitination of BCL2, thereby acting as a positive regulator of autophagy (PubMed:20889974). Promotes the autophagic degradation of dysfunctional depolarized mitochondria (mitophagy) by promoting the ubiquitination of mitochondrial proteins such as TOMM20, RHOT1/MIRO1 and USP30 (PubMed:19029340, PubMed:19966284, PubMed:23620051, PubMed:24896179, PubMed:25527291). Preferentially assembles 'Lys-6'-, 'Lys-11'- and 'Lys-63'-linked polyubiquitin chains following mitochondrial damage, leading to mitophagy (PubMed:25621951). Mediates 'Lys-48'-linked polyubiquitination of ZNF746, followed by degradation of ZNF746 by the proteasome; possibly playing a role in the regulation of neuron death (PubMed:21376232). Limits the production of reactive oxygen species (ROS). Regulates cyclin-E during neuronal apoptosis. In collaboration with CHPF isoform 2, may enhance cell viability and protect cells from oxidative stress (PubMed:22082830). Independently of its ubiquitin ligase activity, protects from apoptosis by the transcriptional repression of p53/TP53 (PubMed:19801972). May protect neurons against alpha synuclein toxicity, proteasomal dysfunction, GPR37 accumulation, and kainate-induced excitotoxicity (PubMed:11439185). May play a role in controlling neurotransmitter trafficking at the presynaptic terminal and in calcium-dependent exocytosis. May represent a tumor suppressor gene.<ref>PMID:10888878</ref> <ref>PMID:10973942</ref> <ref>PMID:11431533</ref> <ref>PMID:11590439</ref> <ref>PMID:12628165</ref> <ref>PMID:12719539</ref> <ref>PMID:15105460</ref> <ref>PMID:15728840</ref> <ref>PMID:16135753</ref> <ref>PMID:17846173</ref> <ref>PMID:18541373</ref> <ref>PMID:19029340</ref> <ref>PMID:19229105</ref> <ref>PMID:19801972</ref> <ref>PMID:19966284</ref> <ref>PMID:20889974</ref> <ref>PMID:21376232</ref> <ref>PMID:21532592</ref> <ref>PMID:22082830</ref> <ref>PMID:23620051</ref> <ref>PMID:23754282</ref> <ref>PMID:23933751</ref> <ref>PMID:24660806</ref> <ref>PMID:24751536</ref> <ref>PMID:24784582</ref> <ref>PMID:24896179</ref> <ref>PMID:25527291</ref> <ref>PMID:25621951</ref>
