Fig 1. Mechanism of p53-DNA interaction upon DNA-contact and rescue mutations.
(A) Shows the normal p53-DNA interaction, leading to cancer suppression. (B) Illustrates how a DNA-contact mutation results in a reduced p53-DNA affinity, which is a possible cause of cancer. (C) Shows that a rescue mutation can restore the good p53-DNA affinity, and thus give again rise to cancer suppression.
