Recombinant human CDC2 protein, also known as Cell Division Cycle 2 kinase (CDK1), is a critical regulator of the eukaryotic cell cycle. Originally identified in yeast, CDC2 is a member of the cyclin-dependent kinase (CDK) family that drives the transition from the G2 phase to mitosis (M phase) by forming a complex with cyclin B. This kinase is essential for initiating chromosomal condensation, nuclear envelope breakdown, and spindle assembly. Its activity is tightly controlled through phosphorylation-dephosphorylation events, binding to regulatory cyclins, and inhibitory interactions with proteins like p21 and p27.
CDC2’s role in cell division makes it a focal point in cancer research, as dysregulation of CDK1 is linked to uncontrolled proliferation. Recombinant versions of CDC2 are produced using genetic engineering in systems like *E. coli* or mammalian cells, enabling studies on its structure, function, and interactions. Researchers utilize this protein to investigate cell cycle checkpoints, DNA damage responses, and apoptosis mechanisms. Additionally, recombinant CDC2 serves as a tool for screening CDK inhibitors, which are potential therapeutic agents for malignancies and other proliferative disorders. Its conserved function across species also provides insights into developmental biology and cellular homeostasis. The availability of active, purified recombinant CDC2 continues to advance both basic and translational biomedical research.
