Depending on the bound cofactor, transcription factors can have either repressing or transactivating activities. To allow a switch between these different states, regulated cofactor exchange has been proposed; however, little is known about the molecular mechanisms that are involved in this process. LIM homeodomain (LIM-HD) transcription factors associate with RLIM (RING finger LIM domain-binding protein) and with CLIM (cofactor of LIM-HD proteins; also known as NLI, Ldb and Chip) cofactors. The co-repressor RLIM inhibits the function of LIM-HD transcription factors, whereas interaction with CLIM proteins is important for the exertion of the biological activity conferred by LIM-HD transcription-factors. Here we identify RLIM as a ubiquitin protein ligase that is able to target CLIM cofactors for degradation through the 26S proteasome pathway. Furthermore, we demonstrate a ubiquitination-dependent association of RLIM with LIM-HD proteins in the presence of CLIM cofactors. Our data provide a mechanistic basis for cofactor exchange on DNA-bound transcription factors, and probably represent a general mechanism of transcriptional regulation</dcterms:abstract> <dc:contributor>Bach, Ingolf</dc:contributor> <dc:contributor>Peirano, Reto I.</dc:contributor> <dc:contributor>Scheffner, Martin</dc:contributor> <dc:contributor>Peters, Marvin A.</dc:contributor> <dc:contributor>Ostendorff, Heather P.</dc:contributor> <dc:contributor>Bossenz, Michael</dc:contributor> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-11-16T09:20:27Z</dcterms:available> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-11-16T09:20:27Z</dc:date> <dc:creator>Peters, Marvin A.</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/16759"/> <dc:creator>Bach, Ingolf</dc:creator> <dc:language>eng</dc:language> <dcterms:bibliographicCitation>Publ. in: Nature ; 416 (2003), 6876. - pp. 99-103</dcterms:bibliographicCitation> <dc:creator>Ostendorff, Heather P.</dc:creator> <dcterms:issued>2002-03-07</dcterms:issued> <dcterms:title>Ubiquitination-dependent cofactor exchange on LIM homeodomain transcription factors</dcterms:title> <dc:creator>Scheffner, Martin</dc:creator> <dc:creator>Peirano, Reto I.</dc:creator> </rdf:Description> </rdf:RDF>
