Hepatocyte growth factor (HGF) is a plasminogen-like protein thought to be a humoral
mediator of liver regeneration. A 145-kilodalton tyrosyl phosphoprotein observed in rapid
response to HGF treatment of intact target cells was identified by immunoblot analysis as the
β subunit of the c-met proto-oncogene product, a membrane-spanning tyrosine kinase.
Covalent cross-linking of 125I-labeled ligand to cellular proteins of appropriate size that
were recognized by antibodies to c-met directly established the c-met product as the cell …
