Cyclin-Dependent Kinases Play Crucial Role in Cell Cycle Regulation

Discovery:

Researchers have shed light on the significance of cyclin-dependent kinases (CDKs), a group of enzymes that regulate cell division and progression through the cell cycle.

Functions:

CDKs are pivotal in various cellular processes, including cell cycle control, transcription, and DNA replication. They function by modifying specific protein substrates involved in cell cycle progression.

Example:

The mitotic cyclin-CDK complex, composed of cyclin cdc13 and cdk cdc2, serves as an example. This complex exists as an inactive entity until activated by specific signals or events within the cell cycle.
