Abstract:
The primary cilium is often associated with the phases G0 and G1 of the cellular cycle in most of the cells. So, recent studies show that its formation and its resorption are closely linked to molecular actors of the cellular cycle, as for example Aurora A or PLK1 (polo-like kinase 1). Furthermore, its resorption seems to be critical for the progress of the phase S and the cellular determination, in particular in the case of neural stem cells. Finally, the primary cilium acts as a cellular antenna allowing to transmit numerous signal pathways which, in their turn, contribute to the cellular fate.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
