Figure 4. Validation of adhesion complex-localized phosphorylation sites.

Figure 4

(a) Immunoblot analyses of the protein complexes isolated from cells spread on FN or Tf for 120 min. Samples were probed using phosphospecific antibodies targeting: paxillin pTyr118; FAK pTyr397, pTyr576 and pTyr407; MYPT1 pThr696; cortactin pTyr421; SHP2 pTyr580; and PKCδ pTyr313. (b) Immunofluorescence images of cells spread on FN for 120 min. Cells were stained using the phosphospecific antibodies FAK pTyr407, cortactin pTyr421 and PKCδ pTyr313 (all green). In each case, cells were also stained using an antibody targeting the focal adhesion marker paxillin (red). Scale bar, 20 μm. (c) Immunoblot analyses of the WCLs of cells spread on FN or Tf for 120 min. Samples were probed using the same antibodies as used to probe isolated complexes in a. Dashed lines in a,c indicate where the images have been cropped for display purposes. White arrows to left of blots highlight the expected MWs of the corresponding proteins. Black arrows to the left of blots highlight a putative high MW isoform of PKCδ.
