Figure 10. Arg regulated phosphorylation of CrkII and paxillin.
A) Arg enhanced, and Arg-MO reduced, phosphorylation of endogenous CrkII and paxillin, but neither significantly affected phosphorylation of Erk. B) Arg was required for activation of CrkII phosphorylation by RTKs. Protein phosphorylation was normalized with the total amount of that protein and the level in the control extracts was considered as 1.
