Target activation of KIBRA promoter P1a by ZFP226. Luciferase-based reporter experiments with ZFP226 co-expression resulted in a significant activation of KIBRA promoter P1a (constructs −316/+186 and −730/+186) compared to pcDNA3.1 mock-control. Site-directed mutagenesis (construct −730/+186 M) prevented the ZFP226 effect. Promoter activity of KIBRA reporter constructs was determined as relative light units and expressed as FI compared to mock-transfection. Transfections are representative for experiments (n = 4). ***p < 0.001; ns, not significant.
