Enhanced potency of human Sonic hedgehog by hydrophobic modification.

Abstract

Post-translational modifications of the developmental signaling protein Sonic hedgehog (Shh) by a long-chain fatty acid at the N-terminus and cholesterol at the C-terminus greatly activate the protein in a cell-based signaling assay. To investigate the structural determinants of this activation phenomenon, hydrophobic and hydrophilic moieties have been… (More)
