WebMPF must be activated in order for the cell to transition from G 2 to M phase. There are three amino acid residues responsible for this G 2 to M phase transition. The Threonine-161 (Thr-161) on CDK1 must be phosphorylated by a CDK-activating kinase (CAK). CAK only phosphorylates Thr-161 when cyclin B is attached to CDK1. In biochemistry, phosphorylation is the attachment of a phosphate group to a molecule or an ion. This process and its inverse, dephosphorylation, are common in biology and could be driven by natural selection. Protein phosphorylation often activates (or deactivates) many enzymes.
