The stability of wild-type p53 is critical for its apoptotic function. In some cancers, wild-type p53 is inactivated by interaction with viral and cellular proteins, and restoration of its activity has therapeutic potential. Here, we identify homeobox Msx1 as a p53-interacting protein and show its novel function as a p53 regulator. Overexpression of homeobox Msx1 induced apoptosis of cancer cells harboring nonfunctional wild-type p53 and suppressed growth of human tumor xenografts in nude mice. The homeodomain of Msx1 functions as a protein-protein interacting motif rather than a DNA-binding domain and is essential for stabilization, nuclear accumulation, and apoptotic function of wild-type p53. The identification of a novel function of Msx1 as a p53 regulator may open new avenues for developing improved molecular therapies for tumors with a nonmutational p53 inactivation mechanism.
