reach
"Hyperphosphorylation of NPM T199 by Cdk2 strongly correlated with constitutive centrosome duplication cycle and centrosome amplification."

sparser
"During the cell cycle, NPM is phosphorylated by cdk2-cyclin E on threonine 199 (T199) which causes the dissociation of NPM away from the centrosome and permits duplication."

reach
"Since HBx is reported to potentiate the activity of CDK2 kinase [41] which phosphorylates NPM at Thr 199 [55], we next monitored the phosphorylation status of NPM in its presence."

reach
"T199 phosphorylation of NPM1 is mediated by the cyclin dependent kinases CDK1 and CDK2, which in turn play a key role in NPM1 dissociation from nucleolar components."

reach
"In our study, HBx induced CDK2 activity increased the phosphorylation of NPM at Thr 199 which correlated well with its increased intracellular stability."

"Furthermore, hyperactive Cdk2 and Cdk4 deregulate the licensing of the centrosome duplication cycle in p53-null cells by hyperphosphorylating nucleophosmin (NPM) at Thr199, as evidenced by observations that ablation of Cdk2, Cdk4, or both Cdk2 and Cdk4 abrogates that excessive phosphorylation."

sparser
"Early work by Fukasawa and collaborators showed that NPM1 is one of the most conspicuous targets of Cdk2 in unduplicated centrosomes and that phosphorylation of NPM1 on T199 by Cdk2-cyclin E leads to its dissociation from centrosomes ( xref , xref )."

sparser
"As previously reported, phosphorylation of NPM1 by CDK2-cyclin E on threonine 199 triggers its dissociation from unduplicated centrosomes in the G1 phase, which promotes initiation of centrosome duplication [ xref ]."

sparser
"After Cdk2 and Cyclin E phosphorylate Thr199 in NPM, NPM dissociates from centrosomes, which in turn triggers centrosome duplication (Grisendi et al., xref )."

reach
"These observations reveal that RABL6A specifically regulates Cdk2 mediated phosphorylation of NPM at T199."

sparser
"Cdk2 phosphorylates NPM on T199 and phosphorylation of this site initiates centrosome duplication."

reach
"In late G1, activated CDK2 and cyclin E phosphorylates NPM1 at T199, causing NPM1 to dissociate from centrosomes, an event essential for centrosome duplication 16."

sparser
"Phosphorylation of NPM1 on Thr199 by cyclin-dependent kinase 2 (CDK2)/cyclin E is critical for the physical separation of the paired centrioles, which triggers the initiation of centrosome duplication [ xref ]."

"30 NPM1 is phosphorylated on Thr199 by Cdk2 and cyclin E late in G 1 phase, 31 which causes dissociation of the majority of NPM1 from the centrosomes, a step required for centrosome duplication to occur."

"NPM1 is phosphorylated at Threonine 199 by the cyclin dependent kinases CDK1 and CDK2 during the cell cycle [XREF_BIBR]."

"One common event leading to centrosome overduplication is cyclin dependent kinase 2 (Cdk2)-mediated hyperphosphorylation of threonine 199 (T199) within nucleophosmin and B23 (NPM) XREF_BIBR, a major regulator of genomic stability XREF_BIBR."

"Previous studies show that CDK4, CDK6 and CDK2 phosphorylate NPM at Thr199 initiating the separation of centrosomes, as the first step in centrosome duplication."

"Previous studies have shown that the human NPM’s phosphorylation by cyclin E–cyclin-dependent kinase 2 (cdk2) on threonine (Thr) 199 regulates its translocation from the centrosome during cell cycle progression."
