GLI3R is a DNA-binding transcriptional repressor that recognizes consensus GLI sites 5'-GACCACCC-3' in the promoters of target genes (Kinzler and Vogelstein, 1990). DNA-binding is mediated through 5 C2H2 Kruppel zinc fingers in the N-terminal region of the protein, which remains intact after proteasome-mediated processing (reviewed in Hui and Angers, 2011). GLI-dependent target genes have been identified by a number of ChIP based screens, and one well established target of GLI3R is the Hh receptor, PTCH1 (Lee et al, 2010; Vokes et al, 2007; Vokes et al, 2008). GLI3R has been shown to bind to a GLI-consensus sequence in the PTCH1 promoter as assesed by electrophoretic mobility shift assay and the protein is able to repress expression of a reporter gene driven by this element (Agren et al, 2004). GLI3R may promote repressive complexes at the PTCH1 promoter by the SKI1-dependent recruitment of HDAC complexes (Dai et al, 2002). Other GLI3R transcriptional targets include GLI1 and GLI2 (Hu et al, 2006).
