During development and tissue homeostasis, cells must integratedifferent signals. We investigated how cell behavior is controlledby the combined activity of transforming growth factorß(TGF-ß) and receptor tyrosine kinase (RTK) signaling,whose integration mechanism is unknown. We find that RTK/Ras/MAPK(mitogen-activated protein kinase) activity induces p53 N-terminalphosphorylation, enabling the interaction of p53 with the TGF-ßactivatedSmads. This mechanism confines mesoderm specification in Xenopusembryos and promotes TGF-ß cytostasis in human cells.These data indicate a mechanism to allow extracellular cuesto specify the TGF-ß gene-expression program.
