NCIt synonyms : HHG1; SHH; Sonic Hedgehog Homolog Protein; HHG-1; Sonic Hedgehog Homolog;
NCIt definition : Sonic hedgehog protein (462 aa, 50 kDa) is encoded by the human SHH gene. This protein
plays a role in embryonic pattern formation.;
NCIt note : The C-terminal domain of sonic hedgehog protein has no signaling activity; however,
it displays autoproteolysis and cholesterol transferase activities. Together these
enzymatic activities catalyze the cleavage of the full-length protein and the covalent
attachment of a cholesterol moiety to the C-terminus of the newly generated N-terminal
fragment (N-product). The N-product is the active species in both local and long-range
signaling. (UniProt);
