Many mitotic kinases rely on spatial targeting to phosphorylate their specific substrates. This restricts the activity of the kinase to generate gradients of kinase activity. The most well characterized spatially-targeted kinases are Aurora A and B kinases and they appear to share the same substrate specificity (Fu et al., 2009). However Aurora

Cdk and Its Role in the Mitotic Cycle? Biology Diagrams

In 1996, Kim Nasmyth 1 proposed that the eukaryotic cell cycle is an alternating sequence of transitions from G 1 to S-G 2-M and back again.These two phases correlate to high activity of cyclin-dependent kinases (CDKs) that trigger S-G 2-M events and CDK antagonists that stabilize G 1 phase. We associated these "alternative phases" with the coexistence of two stable steady states of the

Decades ago, scientists discovered cyclin-dependent kinases (CDKs), proteins that act as master regulators of the cell cycle. As their name indicates, the activity of CDKs is controlled by cyclins

A mitotic stopwatch determines cell fate Biology Diagrams

The most prominent mitotic kinase is the cyclin-dependent kinase 1 ( Cdk1),the founding member of the activity of Cdk2,in association with either cyclin A or cyclin E 1-3.Another kinase,
