Signal transduction involves the presenilin-dependent intracellular processing of Notch and nuclear translocation of the intracellular domain of Notch, Notch-IC. Notch-IC associates with the DNA-binding protein RBP-Jkappa/CBF-1 to activate transcription of Notch target genes. In the absence of Notch signalling, RBP-Jkappa/CBF-1 acts as a transcriptional repressor through the recruitment of histone deacetylase (HDAC) corepressor complexes. We identified SHARP as an RBP-Jkappa/CBF-1-interacting corepressor in a yeast two-hybrid screen. In cotransfection experiments, SHARP-mediated repression was sensitive to the HDAC inhibitor TSA and facilitated by SKIP, a highly conserved SMRT and RBP-Jkappa-interacting protein. SHARP repressed Hairy/Enhancer of split (HES)-1 promoter activity, inhibited Notch-1-mediated transactivation and rescued Notch-1-induced inhibition of primary neurogenesis in Xenopus laevis embryos. Based on our data, we propose a model in which SHARP is a novel component of the HDAC corepressor complex, recruited by RBP-Jkappa to repress transcription of target genes in the absence of activated Notch. Notch-IC associates with the DNA-binding protein RBP-Jkappa/CBF-1 to activate transcription of Notch target genes."; prov:wasQuotedFrom pubmed:12374742 . sub:_6 rdfs:label "Selventa" . sub:assertion prov:hadPrimarySource pubmed:12374742; prov:wasDerivedFrom beldoc:, sub:_5 . } sub:pubinfo { this: dct:created "2014-07-03T14:30:06.349+02:00"^^xsd:dateTime; pav:createdBy orcid:0000-0001-6818-334X, orcid:0000-0002-1267-0234 . }
