EGFR bound to EGFR_ligand increases the amount of EGFR bound to ERBB2. 1 / 1

"The first group includes EGF, amphiregulin (AR), and transforming growth factor-alpha (TGF-alpha), which bind specifically to ErbB1; the second group betacellulin (BTC), heparin-binding EGF (HB-EGF), and epiregulin (EPR), which exhibit dual specificity in that they bind ErbB1 and ErbB4. The third group is composed of the neuregulins (NRG) and forms two subgroups based upon their capacity to bind ErbB3 and ErbB4 (NRG-1 and NRG-2) or only ErbB4 (NRG-3 and NRG-4). ErbB2 has no direct ligand and needs a heterodimerization partner to acquire signaling potential ErbB3...has impaired kinase activity."
