Abstract:
In eukaryotes, the copy number and size of any given organelle compartment remain constant in dividing cells, underlying a tight coordination between cell division and organelle homeostasis. However, in most cases the mechanisms for this coordination remain mysterious. Here we outline a few cases where the cell cycle machinery directly impacts on organelle homeostasis, with emphasis on the control of vacuolar (lysosomal) copy number and size in budding yeast. We also discuss aspects of organelle biology that can profoundly affect certain cell cycle parameters, such as cell size.

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.
