FIG. 3.

c-Jun-mediated transcriptional repression operates through a FOG-independent mechanism. (A) Diagrams of GATA-1, GATA-2, and GATA-1 deletion mutants. (B) Analysis of transcriptional activation by the indicated GATA factors with and without c-Jun. Results ± standard error of the mean of three experiments are shown as relative reporter activity compared with activation by GATA-1 alone, normalized by β- galactosidase expression. For each GATA factor, the activation obtained with that factor alone was set at 100%.
