According to the present invention, Mts-1 interferes with the function of tumor suppressor p53 by binding to p53. The present inventors have demonstrated that binding of Mts-1 inhibits p53 phosphorylation by PKC, represses the DNA-binding activity of p53 and reduces the transactivation capacity of p53. The present invention has further identified that the Mts-1 protein binds to the C-terminal region of p53. Accordingly, the present invention provides compositions and methods useful for treating tumors by, e.g., intercepting the interaction between Mts-1 and p53, or inhibiting the expression or function of Mts-1. |
