Reaction: CAK-mediated phosphorylation of Cyclin A:Cdc2 complexes
- in pathway: Cyclin A/B1/B2 associated events during G2/M transition
Full activity of most CDKs is dependent on CAK mediated phosphorylation at a conserved residue (Thr 161 in Cdc2). This modification is thought to improve substrate binding. High affinity binding of Cyclin A within the Cyclin A:Cdc2 complex requires this phosphorylation (Desai et al 1995).
