Transcriptional properties of GATA4 on the mouse, pig, and human SRY promoters. A. Multiple consensus (but not species conserved) GATA binding motifs are present in the first 2 kilobases of the mouse, human, and pig SRY promoters; the GATA sites are indicated by the lozenges. B. Ability of GATA4 to transactivate the SRY promoter. HeLa cells were co-transfected with either a -1090 bp mouse, -1400 bp pig, or -1250 bp human SRY-luciferase promoter construct (500 ng) along with increasing amounts of a GATA4 expression vector (25, 50, or 100 ng). All promoter activities are reported as fold activation over control ± S.E.M. Like letters indicate no statistically significant difference between groups (P > 0.05). C. Western blot analysis of nuclear extracts (10 μg) from HeLa cells overexpressing GATA4.
