It is believed that loss of DJ-1 function is causative for disease, although the function of DJ-1 still remains a matter of controversy. We show that DJ-1 is localized in the cytosol and is associated with membranes and organelles in the form of homodimers. The disease-related mutation L166P shifts its subcellular distribution to the nucleus and decreases its ability to dimerize, impairing cell survival. Using an intracellular foldase biosensor, we found that wild-type DJ-1 possesses chaperone activity, which is abolished by the L166P mutation. We observed that this aberrant phenotype can be reversed by the expression of the cochaperone BAG1 (Bcl-2-associated athanogene 1), restoring DJ-1 subcellular distribution, dimer formation, and chaperone activity and ameliorating cell survival."],["dc.identifier.doi","10.1083/jcb.200904103"],["dc.identifier.gro","3142963"],["dc.identifier.isi","000274723800009"],["dc.identifier.pmid","20156966"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6087"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/425"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10 / Funder: Deutsche Forschungsgemeinschaft (DFG) [EXC171]"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.issn","0021-9525"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","BAG1 restores formation of functional DJ-1 L166P dimers and DJ-1 chaperone activity"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Recently, we have shown that Bcl-2-associated athanogene-1 (BAG1), a multifunctional co-chaperone, modulates toxicity, aggregation, degradation and subcellular distribution in vitro and in vivo of the disease-specific mutant huntingtin protein. Aiming at future small molecule-based therapeutical approaches, we further analysed structural demands for these effects employing the C-terminal deletion mutant BAG Delta C. We show that disruption of the BAG domain known to eliminate intracellular heat shock protein 70 (Hsp70) binding and activation also precludes binding of Siah-1 thereby leaving nuclear huntingtin translocation unaffected. At the same time BAG Delta C fails to induce increased proteasomal huntingtin turnover and does not inhibit intracellular huntingtin aggregation, a pre-requisite necessary for prevention of huntingtin toxicity."],["dc.identifier.doi","10.3390/molecules15106678"],["dc.identifier.gro","3142847"],["dc.identifier.isi","000283587400001"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6876"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/296"],["dc.notes.intern","WoS Import 2017-03-10 / Funder: CMPB; High Q foundation; European Commission [MEST-CT-2004-504193]"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.issn","1420-3049"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Modulation of Huntingtin Toxicity by BAG1 is Dependent on an Intact BAG Domain"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
