Cdk Control of Mitotic Progression - Rami Rahal - Häftad

further increase as cells enter M phase (Ishii etal., 2010). Phosphorylated Cdt2 is also observed in G1 phase, when cells are irradiated with UV and Cdt1 is degraded. These observa-tions suggest that Cdt2 phosphorylation is related to substrate degradation. The phosphorylation levels during the cell cycle well reflect CDK activity. CDK/cyclin complexes require phosphorylation of a conserved threonine residue in CDKs (T160 in CDK2) for full catalytic activity. Thr160 phosphorylation leads to a rearrangement of the activation loop so that it adopts a conformation that can recognize substrate.

In further drosophila studies, Cdk16 and cdk23 appear to be activated via phosphorylation by Polo-like kinase 1 (Plk1) and its fission yeast counterpart, appear to bind particularly to Cdc23. The complex is understood to be regulated by activators CDC20 and Cdh1 during mitosis.

Phosphorylation of S-CDK substrates leads to the initiation of DNA replication and S phase progression [16,17].

Plant A CDK-activating kinase (CAK) catalyzes the phosphorylation of CDKs to activate and appears to play a role in both G1 to S and G2 to M-phase progression. 6 Dec 2012 A KM value of 3.3 μM and a kcat value of 73 min−1 were determined for Clb5- Cdk1-dependent phosphorylation for Sic1 (data not shown).

As M-Cdk gets degraded later in mitosis, Cdc20 gets released and Cdh1 can bind to APC/C, keeping it activated through the M/G 1 transition. M-Cdk phosphorylates lamins, the proteins that make up the nuclear lamina. Phosphorylation of lamins leads to disassembly of the nuclear lamina, leading to breakdown of the nuclear envelope.
