YB-1 inhibits cap-dependent and cap-independent translation. CEF, expressing proteins encoded by RCAS vectors as indicated, were transiently transfected with pHCV-IRES containing the bicistronic reporter CAT/luc. Luciferase activity reflects internal ribosome entry site-dependent translation (); CAT activity represents cap-dependent translation (▪). Experiments were carried out three times; standard deviations are shown as error bars. The translational activity of cells transfected with the empty vector was designated 1.0.
