ARF (also known as p14ARF in the human and p19ARF in the mouse) is an alternative transcript of the INK4a/ARF tumour-suppressor locus that encodes p16INK4a, an inhibitor of cyclin dependent kinases. ARFs are tumour suppressors participating in p53-dependent or independent pathways that restrain abnormal cell growth and maintain genomic stability [PMID: 25723571, PMID: 16600663,PMID: 12660818]. ARF interacts with MDM2 and neutralizes MDM2's inhibition of p53 [PMID: 11331246]. Mdm2 may also regulate ARF turnover by mediating its degradation through the proteasome [PMID: 25723571]. p14ARF has also been shown to interact with E2F factors to form p14ARF-E2F/partner-DNA complexes repressing E2F-dependent transcription [PMID: 20082327].
