CDK1

CDK1 (cyclin-dependent kinase 1) is a highly conserved serine/threonine kinase that functions as a central regulator of eukaryotic cell-cycle progression through cyclin-dependent substrate phosphorylation, particularly during G2/M transition and mitosis[1][2]. Mechanistically, CDK1 forms active complexes with cyclins and coordinates centrosome dynamics, chromosome segregation, spindle organization, and mitotic progression through phosphorylation-dependent signaling networks[2][3]. CDK1 also regulates translational control during mitosis by directly phosphorylating key components of the protein synthesis machinery, including 4E-BP1, thereby linking cell-cycle progression with cellular growth programs[4][5]. In disease models, aberrant CDK1 activity contributes to tumor-cell proliferation, and elevated dependence on CDK1-mediated mitotic signaling has supported its investigation as a therapeutic target across multiple malignancies[6][7]. Compared with related cyclin-dependent kinase isoforms, CDK1 is distinguished by its indispensable role in driving mitotic entry and execution, making it a critical node for cell-cycle control and experimental interrogation of mitotic mechanisms[1][2]. For experimental applications, the ATP-competitive inhibitor RO-3306 is widely used to achieve reversible CDK1 suppression, inducing G2/M arrest and enabling mechanistic studies of mitotic regulation, DNA-damage responses, apoptosis, and cancer-cell vulnerability[6][8]. Furthermore, pharmacological inhibition of CDK1 blocks phosphorylation-dependent oncogenic functions of downstream substrates, including SET isoform 1, which regulates mitotic fidelity, cell migration, invasion, and tumor growth in cellular and xenograft models[3][6].
