Influence of ∆p53α isoforms with inducible expression on transactivation activity of constitutively expressed FLp53α. (A) in media with 0.2 % galactose; (B) in media with 2% galactose. Four isogenic yeast strains were used, with the p53 target site (PUMA), with the p53 target site after G4 forming sequence (G4-PUMA), with the p53 target site before G-quadruplex forming sequence (PUMA-G4), and the G4 forming sequence upstream of the luciferase gene. Asterisks indicate a significant induction of p53-dependent transactivation (p < 0.05).
