Function
May be involved in macrophage-mediated cellular proliferation. It is mitogenic for fibroblasts and smooth muscle but not endothelial cells. It is able to bind EGF receptors with higher affinity than EGF itself and is a far more potent mitogen for smooth muscle cells than EGF. Also acts as a diphtheria toxin receptor. -
Sequence similarities
Contains 1 EGF-like domain. -
Post-translational
modificationsSeveral N-termini have been identified by direct sequencing. The forms with N-termini 63, 73 and 74 have been tested and found to be biologically active.
O-linked glycan attachment sites were determined by Edman degradation, O-glycanase digest suggests mucin-type glycosylation (done in HB-EGF purified from histiocytic lymphoma cell line U-937). -
Cellular localization
Cell membrane and Secreted > extracellular space. Mature HB-EGF is released into the extracellular space and probably binds to a receptor. - Information by UniProt

MW ~10.1 kDa. -
The ED50 was determined by cell proliferation assay (using balb/c 3T3) and was found to be ≤1.0ng/ml, corresponding to a specific activity of ≥ 1×106 units/mg.
