To obtain a global view of DYRK1A-regulated pathways, we analysed the proteomes and phosphoproteomes of U251 glioblastoma cells infected with doxycycline-inducible DYRK1A shRNA (Fig. 1A) or treated with DYRK1A inhibitors leucettine 41 (L41, IC50 = 40 nM)21 and ALGERNON (ALG, IC50 = 77 nM)22. … See more CDK1 activity is controlled by precise regulation of cyclin B levels and CDK1 phosphorylation. Phosphorylation of CDK1 on residue T161 induces the conformational … See more To investigate DYRK1A-CDK1 pathway in clinically relevant models, we knocked down DYRK1A in four patient-derived glioblastoma stem cell lines (Fig. 5A)34. Surprisingly, … See more Since the CDK1/cyclin B complex is the master regulator of mitosis and pathway analysis indicates activation of mitosis upon DYRK1A inhibition (Fig. 2H), we next investigated the … See more Finally, we questioned whether DYRK1A inhibition reactivates the cell cycle in dormant cancer cells, which create a pool of drug-tolerant persister cells surviving anti-proliferative … See more WebOct 23, 2003 · We identified about 200 Cdk1 substrates, several of which are phosphorylated in vivo in a Cdk1-dependent manner. The identities of these substrates reveal that Cdk1 employs a global regulatory strategy involving phosphorylation of other regulatory molecules as well as phosphorylation of the molecular machines that drive …
