1 Specific phosphorylation of nucleophosmin on Thr(199) by cyclin-dependent kinase 2-cyclin E and its role in centrosome duplication. Threonine cyclin dependent kinase 2 Homo sapiens
2 Here, we identified that threonine 199 (Thr(199)) of NPM/B23 is the major phosphorylation target site of CDK2-cyclin E in vitro, and the same site is phosphorylated in vivo. Threonine cyclin dependent kinase 2 Homo sapiens
3 Here, we identified that threonine 199 (Thr(199)) of NPM/B23 is the major phosphorylation target site of CDK2-cyclin E in vitro, and the same site is phosphorylated in vivo. Threonine cyclin dependent kinase 2 Homo sapiens
4 These observations provide direct evidence that the CDK2-cyclin E-mediated phosphorylation on Thr(199) determines association and dissociation of NPM/B23 to the centrosomes, which is a critical control for the centrosome to initiate duplication. Threonine cyclin dependent kinase 2 Homo sapiens
