Suppressor of Fused Proteins and Enzymes

The Hedgehog (Hh) signaling pathway has conserved roles in development of species ranging from Drosophila to humans. Human supressor of fused HSu(Fu) acts as a negative regulator in the hedgehog signaling (SHH) pathway by down-regulating GLI1-mediated transactivation of target genes (1). HSu(fu) was found to repress activity of the zinc-finger transcription factor Gli, which mediates Hedgehog signaling in vertebrates, and to physically interact with Gli, Gli2 and Gli3 (2). The sonic hedgehog ...
