Gene Information

Biochem/physiol Actions

Heparin-binding epidermal growth factor (HB-EGF), like BTC, is a heparin-binding EGF family member. Natural soluble HB-EGF is a 19 kDa glycoprotein of multiple forms due to heterogeneous truncations. Soluble HB-EGF is mitogenic and chemotactic for fibroblasts, keratinocytes, and smooth muscle cells but not capillary endothelial cells. Production of HB-EGF is detected in monocytes, macrophages, and vascular and aortic smooth muscle cells (SMC). HB-EGF may play a role in the pathogenesis of atherosclerosis. It may also be an effector of Jun-induced oncogenic transformation. HB-EGF binds to EGFR with high affinity and to ErbB with moderate affinity.

Physical form

Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline containing 2.5 mg bovine serum albumin.

Analysis Note

The biological activity is measured by its ability to stimulate 3H-thymidine incorporation in the EGF-responsive BALB/3T3 cells.

Heparin-binding epidermal growth factor-like growth factor (HB-EGF) transduces mitogenic signals through the EGF receptor (EGFR). There are two forms of HB-EGF, the membrane-anchored form (pro-HB-EGF) and the soluble form (sHB-EGF). We studied the biological activity of pro-HB-EGF by using a

Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a widely expressed EGF superfamily member that induces mitogenic and/or chemotactic activities toward different cell types through binding to EGF receptors 1 or 4. Membrane-bound HB-EGF exerts growth activity and adhesion capabilities

Preincubation of Vero cells with 1 microM phorbol 12-myristate 13-acetate (PMA) decreased the specific binding of diphtheria toxin by about 50%, whereas the toxic effect, endocytic uptake and membrane translocation were completely blocked. Toxin bound to PMA-treated cells was released

Signalling through epidermal growth factor (EGF) receptor leads to several cellular responses including cell division and cell migration. Since EGF receptors are expressed on normal mesothelial cells, this study investigated whether EGF receptor ligands act as chemoattractants on these cells.
