Ras is the most frequently activated oncogene found in human cancer, but its mechanisms of action remain only partially understood. Ras activates multiple signaling pathways in order to promote transformation, but can also exhibit a potent ability to induce growth arrest and death. NORE1A (RASSF5) is a direct Ras effector that acts as a tumor suppressor promoting senescence and apoptosis. Its expression is frequently lost in human tumors and its mechanism of action remains unclear. Here I show that NORE1A forms a direct, Ras regulated, complex with β-TrCP, the substrate recognition component of the SCF-β-TrCP ubiquitin ligase complex. NORE1A also …
