Fig. 4. AKT mediates phosphorylation of EphA2 at Ser897 which then promotes binding to EGFR in the presence of Ephexin1.

For each experiment, immunoprecipitation was carried out with protein extracts from the indicated HEK293T cell lines using anti-Flag antibody and then the precipitate was analyzed by western blot analysis using antibodies indicated in the panels. a Extracts from cells co-transfected with Flag-EphA2, V5-EGFR and HA-K-Ras (WT, G12V, and Q61L) plasmids. b Extracts from cells transfected with Flag-tagged EphA2, V5-tagged EGFR along with or without Myc-tagged myr-AKT (constitutively active). c Extracts from cells co-transfected with Flag-tagged Ephexin1 with or without HA-tagged K-RasG12V plasmids. d Extracts from cells transfected with Flag-tagged EphA2 WT or S897D plasmids. e Extracts from cells co-transfected with Flag-tagged Ephexin1 and V5-tagged EphA2 that were treated with EGF (100 ng/ml) after 16 h serum starvation. Western blot analysis was carried out using anti-EphA2 pSer897 antibody. f Extracts from cells co-transfected with Flag-tagged EphA2 WT or S897D, V5-tagged EGFR with or without shEphexin1 plasmids.
