HBEGF (Proheparin-binding EGF-like growth factor)

FEATURES

DESCRIPTION

Also known as HBEGF_CHLAE, HBEGF, DTR, HEGFL. 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 (By similarity). Interacts with EGFR and ERBB4 (By similarity). Interacts with FBLN1.
