"NPM phosphorylation at Thr234/237 is the only NPM phosphorylation site that spotted on this phospho-peptide array which is specifically phosphorylated by CDK1 (Figure 1B). Western blot analysis confirmed elevated p-NPM-Thr234/237 and CDK1 in PLC/PRF/5-LM cells using a phospho-NPM (Thr234/237) specific antibody (Biolegend) (Figure 1C)."
"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."
"We further demonstrate that phospho-mkk1/mkk2 antibodies recognize npm on the c-terminal region, which is phosphorylated by cdc2 (cell division control kinase-2) during g2/m-phase. biochemical and immunocytochemistry analyses verified that the phospho-mkk1/mkk2 antibodies cross-reacted with npm that was phosphorylated at thr234 and thr237 during g2/m-phase, which are the same sites that are targeted by cdc2 (cell division cycle protein-2) during mitosis."
