Figure S5. Lysates from v-Src transformed MTLn3 cells stably expressing control or calpain 2 siRNA were analyzed for cortactin cleavage by Western blotting and probed for cortactin and ERK as a loading control. Arrows indicate calpain 2–dependent cortactin cleavage products. Numbers to the left indicate molecular mass standards in kD.
