Turning a tumor suppressor into a target Tumor-suppressor genes such as TP53 (tumor protein P53) play key roles in the pathogenesis of cancer but, unfortunately, they are difficult to target because they do not create an overactive protein that can be inhibited with a drug. Hsiue et al. discovered a way to target a cancer-associated mutant form of the p53 protein using the body's own immune system (see the Perspective by Weidanz). The authors identified a distinct fragment of this mutant protein, characterized the structural basis for its presentation to T cells, and designed a bispecific antibody to stimulate T cell killing of p53-mutant cancer cells.
