A Novel Interaction between Pyk2 and MAP4K4 Is Integrated with Glioma Cell Migration
Figure 3
Pyk2 coimmunoprecipitates with MAP4K4. (a) Cells cotransfected with FLAG-epitope-tagged Pyk2 FERM and HA-epitope-tagged MAP4K4(143) were lysed and immunoprecipitated with anti-FLAG antibody or normal mouse IgG. Immunoprecipitates were immunoblotted (IB) with anti-FLAG or anti-HA. WCL: whole cell lysate. (b) Cells were cotransfected with FLAG-epitope-tagged MAP4K4(143) and either HA-tagged Pyk2 or HA-tagged FAK, lysed, and immunoprecipitated with mouse IgG or anti-FLAG antibody. Immunoprecipitates or WCL were immunoblotted as indicated. (c) Cells cotransfected with FLAG-tagged Pyk2 and either HA-tagged MAP4K4(143) or HA-tagged full length (FL) MAP4K4 were lysed and immunoprecipitated with rabbit IgG or anti-HA antibody. Immunoprecipitates or whole cell lysate (WCL) was immunoblotted with the indicated antibodies. (d) SF767 glioma cells were lysed and immunoprecipitated with anti-MAP4K4 antibody. Immunoprecipitates or whole cell lysate (WCL) was immunoblotted with the indicated antibodies.
