DALIS scatter randomly throughout the cytosol and serve as antigen storage sites synchronising DC maturation and antigen presentation. Maturation of DCs is accompanied by the induction of the ubiquitin-like modifier FAT10 that localises to aggresomes that are structures similar to DALIS. FAT10 is conjugated to substrate proteins and serves as a signal for their rapid and irreversible degradation by the 26S proteasome similar to, yet independently of ubiquitin, thereby contributing to antigen presentation. Here we have investigated whether FAT10 is involved in the formation and turnover of DALIS and whether proteins accumulating in DALIS can be FAT10ylated. We found that FAT10 localises to DALIS in maturing DCs and that this localisation occurs independently of its conjugation to substrates. Additionally, we investigated the DALIS turnover in FAT10-deficient and -proficient DCs and observed FAT10-mediated disassembly of DALIS. Thus, we report further evidence that FAT10 is involved in antigen processing which may provide a functional rationale why FAT10 is selectively induced upon DC maturation.</dcterms:abstract> <dc:contributor>Krueger, Wolfgang A.</dc:contributor> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2020-06-23T08:02:35Z</dc:date> <dc:creator>Legler, Daniel F.</dc:creator> <dc:contributor>Rossy, Jérémie</dc:contributor> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/49973"/> <dc:contributor>Groettrup, Marcus</dc:contributor> <dc:creator>Mueller, Stefanie</dc:creator> <dcterms:rights rdf:resource="https://rightsstatements.org/page/InC/1.0/"/> <dc:creator>Schregle, Richard</dc:creator> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> <dc:rights>terms-of-use</dc:rights> <dc:creator>Rossy, Jérémie</dc:creator> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> </rdf:Description> </rdf:RDF>
