GST-PKM2 wild-type or the Tyr105Phe mutant was incubated in an in vitro kinase assay in the presence or absence of active FGFR1. Western blot analysis was performed using Phospho-PKM2 (Tyr105) Antibody and a phospho-Tyr antibody. The data demonstrate the specificity of the Phospho-PKM2 (Tyr105) Antibody and that the Tyr105Phe mutation abolishes PKM2 phosphorylation at Tyr105 by FGFR1 in vitro.

Western blot analysis of NCI-H1299 cells using Phospho-PKM2 (Tyr105) Antibody, total PKM2 Antibody #3198, total FGFR1 antibody, phospho-Tyr antibody, and β-actin antibody. The data demonstrate that inhibition of FGFR1 by TKI258 treatment in NCI-H1299 cells results in decreased Tyr105 phosphorylation of endogenous PKM2. (Adapted from Hitosugi, T. et al., 2009).
