In conjunction with previously published data on c-Raf -induced phosphorylation of GABP factors (E.Flory, A. Hoffmeyer, U.Smola, U.R.Rapp, and J.T.Bruder, J.Virol.70:2260- 2268, 1996), these results indicate a contribution of GABP factors to the Raf -mediated enhancement of IL-2 induction during T-cell activation .
