Structural insights into hedgehog ligand sequestration by the human hedgehog-interacting protein HHIP

Hedgehog (Hh) signaling molecules are involved in multiple developmental processes. Hedgehog-interacting protein (Hhip) binds and inhibits vertebrate Hh proteins. Structures of HHIP in complex with SHH and DHH now show a distinct binding site from previous ligand structures, with metal-binding sites...
