Antagonism of Myc functions by Arf
Abstract
The Arf-Mdm2-p53 tumor suppressor pathway is activated by sustained hyperproliferative signals emanating from oncoproteins such as Myc. A recent study reveals a novel level of feedback control, whereby induced p19(Arf) binds to Myc and blocks cell proliferation by selectively impairing its transactivation functions.
