WebJul 9, 2010 · We find that activation of Aurora A first occurs at centrosomes at late G (2) and is required for centrosome separation independently of Cdk1 activity. Upon entry … WebEntry into mitosis is triggered by the activation of cyclin-dependent kinase 1 (Cdk1). This simple reaction rapidly and irreversibly sets the cell up for division. Even though the core step in triggering mitosis is so simple, the regulation of this cellular switch is highly complex, involving a large number of interconnected signalling cascades.

On the assembly of the mitotic spindle, bistability and hysteresis

WebCyclin B is a member of the cyclin family. Cyclin B is a mitotic cyclin. The amount of cyclin B (which binds to Cdk1) and the activity of the cyclin B-Cdk complex rise through the cell cycle until mitosis, where they fall abruptly due to degradation of cyclin B (Cdk1 is constitutively present). The complex of Cdk and cyclin B is called maturation promoting … WebThe cyclin-dependent kinase 1 (Cdk1), formerly called Cdc2 (or p34(Cdc2)), interacts with cyclin B1 to form an active heterodimer. The activity of Cdk1 is subjected to a complex spatiotemporary regulation, required to guarantee its scheduled contribution to the mitotic prophase and metaphase.
