Twist is basic helix-loop-helix transcription factor that binds to E-boxes in gene promoters. Twist possesses an oncogenic function by interfering with the tumor suppressor function of p53. Using a membrane pull-down assay, we found that Twist directly interacts with p53 and that this interaction underlies the inhibitory effects on p53 target gene expression. Twist interacted with the DNA-binding domain of p53 and suppressed the DNA-binding activity of p53. Transcriptional activation of the p21… CONTINUE READING
