Dual intracellular signaling by proteolytic cleavage of membrane-anchored heparin-binding EGF-like growth factor

Cytokine Growth Factor Rev. 2004 Feb;15(1):13-9. doi: 10.1016/j.cytogfr.2003.10.002.

Abstract

Heparin-binding EGF-like growth factor (HB-EGF), a member of the EGF family, is synthesized as a membrane-anchored precursor (proHB-EGF) that is cleaved to release a soluble HB-EGF by specific metalloproteases. Proteolytic cleavage of proHB-EGF yields amino- and carboxy-terminal fragments (HB-EGF and HB-EGF-C). Recent studies indicate that the processing of proHB-EGF is strictly regulated and involved in a variety of biological processes and that not only HB-EGF but also HB-EGF-C functions as a signaling molecule. ProHB-EGF generates dual intracellular signaling molecules by its proteolytic cleavage.
