Structural basis for inhibition of the cyclin-dependent kinase Cdk6 by the tumour suppressor p16INK4a

Russo, Alicia A., Tong, Lily, Lee, Jie-Oh, Jeffrey, Philip D., Pavletich, Nikola P.·1998·Nature

Abstract

The cyclin-dependent kinases 4 and 6 (Cdk4/6) that control the G1 phase of the cell cycle and their inhibitor, the p16INK4a tumour suppressor, have a central role in cell proliferation and in tumorigenesis. The structures of Cdk6 bound to p16INK4a and to the related p19INK4d reveal that the INK4 inhibitors bind next to the ATP-binding site of the catalytic cleft, opposite where the activating cyclin subunit binds. They prevent cyclin binding indirectly by causing structural changes that propagate to the cyclin-binding site. The INK4 inhibitors also distort the kinase catalytic cleft and interfere with ATP binding, which explains how they can inhibit the preassembled Cdk4/6-cyclin D complexes as well. Tumour-derived mutations in INK4a and Cdk4 map to interface contacts, solidifying the role of CDK binding and inhibition in the tumour suppressor activity of p16INK4a.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The same kind of ATP-binding-site distortion has been seen in CDK6 crystals bound to p16INK4a or p19INK4d.

    “A similar structural distortion of the ATP-binding site has been reported in the crystal structure of CDK6 bound to the tumor suppressor p16 INK4a or p19 INK4d (Brotherton et al , 1998; Russo et al , 1998).”
  • In CDK6, INK4 inhibitors occupy a site adjacent to the ATP pocket, opposite the activating cyclin, and indirectly block cyclin binding while lowering ATP affinity through allosteric changes.

    “In the structure, the INK4 inhibitors bind next to the ATP-binding site, opposite where the activating cyclin binds, and thereby not only prevent cyclin binding indirectly but also reduce the affinity of the kinase for ATP by causing extensive allosteric changes in CDK6.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
