p19ARF/CDKN2A: Proteins and Enzymes

p19ARF (mouse) and p14ARF (human) has become an important player in cell cycle regulation. In mice, tumor suppressor effects appear to be mediated by interactions between p19ARF and the p53 tumor suppressor protein. p19ARF counters uncontrolled proliferation and oncogenic signals in p53 dependent pathways. Proteins encoded by the INK4a/ARF locus al...
