"Both subtypes of B23 proteins were phosphorylated during mitosis by cyclin B/cdc2. The RNA binding activity of B23.1 was repressed through cyclin B/cdc2-mediated phosphorylation at specific sites in B23. Thus, the RNA binding activity of B23.1 is stringently modulated by its phosphorylation and subtype association."

"10 CDK1 phosphorylates NPM at the beginning of mitosis at Thr199 and Thr234/237, resulting in inhibition of NPM RNA binding activity."

"We have recently found that nucleophosmin (npm/b23), a phosphoprotein primarily found in nucleolus, associates with unduplicated centrosomes and is a direct substrate of cdk2-cyclin e in centrosome duplication."
