Know domains of E1A-13S (CR1, CR2, CR3 and CR4 and the N-terminal region) are shown as boxes. Numbers indicate positions in aa. and SW613-3 (T) or SW613-B3 (NT) cells were transfected with plasmid pK18(80)luc alone (none) or in the presence of the indicated E1A constructs. Luciferase activities are expressed relative to that obtained with the pK18(80)luc plasmid alone. Error bars represent the standard deviation of the mean of at least two experiments.
