What are the three parts of maturation promoting factors?

Maturation promoting factors (MPFs) consist of three main components: cyclins, cyclin-dependent kinases (CDKs), and the MPF complex itself. Cyclins are proteins that regulate the cell cycle's progression by activating CDKs, which are essential enzymes that drive the cell through various phases. When cyclins bind to CDKs, they form the active MPF complex, which then initiates processes like DNA replication and mitosis. This interplay ensures proper cell division and maturation in eukaryotic cells.
