p19ras brings a new twist to the regulation of p73 by Mdm2.

Abstract excerpt

p53 is the most commonly mutated gene in human cancer. It is now known that the p53 family proteins p63 and p73 play important roles in tumor suppression as well as in development. Because p63 and p73 are rarely mutated in human cancer, understanding the signaling pathways that activate p63 and p73 will not only shed light on the developmental processes regulated by p63 and p73 but may also yield insight into...
