Enhanced v-Src-induced paxillin phosphorylation is attenuated by FAK. Lysates from adherent or suspension cultures of FAK+/+[puro], FAK-/-[puro], FAK+/+[v-Src] and FAK-/-[v-Src] cells were probed by IB for total paxillin, paxillinpoY31, paxillinpoY118 or GAPDH. These data are typical of at least three independent experiments.
