Abstract

Phosphorylation of cyclin-dependent kinases (CDKs) by the CDK-activating kinase is required for the activation of CDK enzymes. Members of two families of CDK inhibitors, p16/p18 and p21/p27, become physically associated with and inhibit the activity of CDKs in response to a variety of growth-modulating signals. Here, we show that the representative members of both families of CDK inhibitors, p21waf1,cip1, p27kip1, and p18, can prevent the phosphorylation of their CDK partners, CDK2 and CDK6, by CDK-activating kinase. No direct interaction between CDK-activating kinase and the CDK inhibitors could be detected, suggesting that binding of these CDK inhibitors to CDK subunits renders CDK inaccessible to the CDK-activating kinase phosphorylation. These findings suggest that a general mechanism of CDK inhibitor function is to block the phosphorylation of CDK enzymes by CDK-activating kinase.

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.
