As we found EphA2 Ser 897 to be in complex with Ephrin B3 in NSCLC cells in vitro and given that such phosphorylation also was reported in NSCLC in vivo in context of EGFR-mutation [31], we think that further analyses of NSCLC material with respect to this interaction should be pursued. The gene discussed is EGFR; the disease is non-small cell lung carcinoma.
