Figure 5. Mapping of GATA4 and PIAS1 domains required for IFABP coactivation.
Transient cotransfections were performed in subconfluent HCT116 cells using wild-type and deletion mutants of GATA4 and wild-type PIAS1 (panel A). In panel B, wild-type and deletion mutants of PIAS1 and wild-type GATA4 were used for cotransfections. Lysates were assayed for luciferase activity 48 hours post-transfection. Results from 3 experiments done in triplicates are shown as meanĀ±SEM.
