Protein Structure

UniProt Annotation

Function

Growth factor that mediates its effects via EGFR, ERBB2 and ERBB4. Required for normal cardiac valve formation and normal heart function. Promotes smooth muscle cell proliferation. May be involved in macrophage-mediated cellular proliferation. It is mitogenic for fibroblasts, but not endothelial cells. It is able to bind EGF receptor/EGFR 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.

Subcellular Localization

Heparin-binding EGF-like growth factor: Secreted, extracellular space. Note=Mature HB-EGF is released into the extracellular space and probably binds to a receptor.Proheparin-binding EGF-like growth factor: Cell membrane; Single-pass type I membrane protein.

Disease Associations

Tissue Specificity

Most abundant in kidney, skeletal muscle, lung, spleen, brain and heart.
