靶點詳情

  • 功能：

    1. in Caco-2 CFTR-shRNA cells, the EGFR ligand EREG is overexpressed due to an active IL-1beta autocrine loop that indirectly activates EGFR, constituting new signaling effectors for the CFTR signaling pathway, downstream of CFTR, Cl(-) , and IL-1beta. PMID: 29091309
    2. we showed that epidermal growth factor receptors (EGFR) were constitutively activated in metastatic lung subtypes of salivary adenoid cystic carcinoma cells, and that this activation was induced by autocrine expression of epiregulin PMID: 26958807
    3. Study shows how the EGFR ligands epiregulin (EREG) and epigen (EPGN) stabilize different dimeric conformations of the EGFR extracellular region.
