In contrast, Sonic hedgehog (Shh) signaling from the posterior zone of polarizing activity blocks Gli3 processing and then induces the expression of Gli3 target genes, including Gli1. Transcription factor Glioblastoma-3 (Gli3) is cleaved in the anterior region of the limb bud to generate its repressor form. The Polycomb repressor complex does not regulate most GLI enhancers GLI activators have been shown to recruit demethylases that remove H3K27me3, a hallmark of the Polycomb repressor complex (PRC2) to promote transcriptional activation of several HH target genes, most notably Gli1 and Ptch1 (Margueron and Reinberg, 2011; Shi et al., 2014; Here we report that the Ski corepressor binds to Gli3 and recruits the histone .
