AIPL1 has previously been shown to interact with NUB1, which facilitates the proteasomal degradation of proteins modified with the ubiquitin-like protein FAT10. Here we report that AIPL1 binds non-covalently to free FAT10 and FAT10ylated proteins and can form a ternary complex with FAT10 and NUB1. In addition, AIPL1 antagonised the NUB1-mediated degradation of the model FAT10 conjugate, FAT10-DHFR, and pathogenic mutations of AIPL1 were defective in inhibiting this degradation. While all AIPL1 mutants tested still bound FAT10-DHFR, there was a close correlation between the ability of the mutants to interact with NUB1 and their ability to prevent NUB1-mediated degradation. Interestingly, AIPL1 also co-immunoprecipitated the E1 activating enzyme for FAT10, UBA6, suggesting AIPL1 may have a role in directly regulating the FAT10 conjugation machinery. These studies are the first to implicate FAT10 in retinal cell biology and LCA pathogenesis, and reveal a new role of AIPL1 in regulating the FAT10 pathway.</dcterms:abstract> <dc:contributor>Gröttrup, Marcus</dc:contributor> <dcterms:issued>2012</dcterms:issued> <dc:contributor>Bett, John S.</dc:contributor> <dc:creator>Richet, Emma</dc:creator> <dcterms:available rdf:datatype="">2013-03-01T13:46:17Z</dcterms:available> <dcterms:hasPart rdf:resource=""/> <dc:contributor>Schmidtke, Gunter</dc:contributor> <dc:creator>van der Spuy, Jacqueline</dc:creator> </rdf:Description> </rdf:RDF>
