What does the combination mitotic cyclin with CDK signal?

The combination of mitotic cyclin with cyclin-dependent kinase (CDK) signals the cell to enter mitosis, initiating the process of cell division. This complex activates CDK, leading to the phosphorylation of target proteins that promote chromatin condensation, spindle formation, and other key events necessary for mitosis. The precise regulation of this cyclin-CDK complex is crucial for ensuring that the cell divides accurately and at the appropriate time in the cell cycle.
