The VEGFR-3(I1053F) mutant is tyrosine kinase inactive. (A) The alignment of the human and mouse VEGFR-3 amino acid sequences showing the lymphedema-linked human mutations (bold) and the I1053F mutation found in the Chy mice (red). (B) Localization of the I1053F mutation within the catalytic domain of the ligand-bound VEGFR-3 heterodimer. (C) VEGFR-3(I1053F) is kinase inactive. We transfected cells with Mock, WT, or I1053F VEGFR-3 expression vectors and analyzed VEGFR-3 by immunoprecipitation and Western blotting of the cell lysates using phosphotyrosine antibodies (Upper). We also confirmed the expression of similar amounts of VEGFR-3 (Lower).
