Webb1 feb. 2014 · Function, structure, and polymorphisms of the INK4/ARF locus. A, p15 INK4b and p16 INK4a both function in the RB tumor suppressor pathway through inhibition of CDK4/6 activity. Expression of p14 ARF inhibits the E3 ubiquitin ligase activity of MDM2, leading to stabilization of p53. The p53 and RB pathways play integral roles in blocking … Webb31 dec. 2016 · Benjamin W Darbro. The protein products of the INK4a/ARF gene locus, p16INK4a and ARF, activate distinct protective checkpoints that inhibit cell proliferation and maintain genomic stability in ...

Differential effects of Ink4a and Arf dosage and derepression in Bmi1-/-lymphoid organs. (A) Splenocyte counts are dramatically reduced in Bmi1-/-mice.Heterozygosity for Arf or Ink4a/Arf partially rescues this phenotype (p < 0.01) but complete loss of Arf or Ink4a/Arf results in a better partial rescue.p53 loss also induces a partial rescue.
