Mouse HB-EGF Antibody (891808R)

Heparin-binding EGF-like growth factor, HB-EGF, is a 19-23 kDa glycoprotein, member of the EGF family of mitogens that exists in multiple forms as a result of heterogenous O-glycosylation.  HB-EGF is a growth factor that mediates its effects via EGFR, ERBB2 and ERBB4. It is required for normal cardiac valve formation and normal heart function and promotes smooth muscle cell proliferation. HB-EGF may be involved in macrophage-mediated cellular proliferation. The cDNA for mouse Proheparin-binding EGF-like growth factor encodes a 208 amino acid residue transmembrane protein that is proteolytically cleaved to generate the soluble HB‑EGF. Like EGF, TGF-alpha, and AR, HB-EGF binds to the EGF receptor and activates the receptor tyrosine kinase. It has been suggested that the differential activities found for HB-EGF compared to EGF may be mediated by the heparin-binding properties of HB-EGF.
