There is increasing evidence that p21(Cip1) and p27(Kip1) are requisite positive regulators of cyclin D1.CDK4 assembly and nuclear accumulation. Both Cip and Kip proteins can promote nuclear accumulation of cyclin D1, but the underlying mechanism has not been elucidated. We now provide evidence that p21(Cip1) promotes the nuclear accumulation of cyclin D1 complexes via inhibition of cyclin D1 nuclear export. In vivo, we demonstrate that p21(Cip1) can inhibit glycogen synthase kinase 3 beta-triggered cyclin D1 nuclear export and phosphorylation-dependent nucleocytoplasmic shuttling. Furthermore, we find that cyclin D1 nuclear accumulation in p21/p27 null cells can be restored through inhibition of CRM1-dependent nuclear export. The ability of p21(Cip1) to inhibit cyclin D1 nuclear export correlates with its ability to bind to Thr-286-phosphorylated cyclin D1 and thereby prevents cyclin D1.CRM1 association.
