Suppressor of fused homolog (Sufu)

Negative regulator in the hedgehog/smoothened signaling pathway (PubMed:16155214, PubMed:16459298). Down-regulates GLI1- mediated transactivation of target genes.

Section of a corepressor complex that acts on DNA-bound GLI1. May also act by linking GLI1 into BTRC and thereby targeting GLI1 to degradation by the proteasome.
