MET interacts with Recepteur d’Origine Nantais (RON), Receptor Tyrosine Kinase-Like Orphan Receptor 1 (ROR1), the human epidermal growth factor receptor (HER) family, which includes EGFR/HER1, HER2/ErbB2, and HER3/ErbB3, the vascular endothelial growth factor receptor (VEGFR), and several other RTKs, forming complex signaling networks that influence tumor biology and therapy resistance. The gene discussed is ROR1; the disease is neoplasm.
