Variation in the time of expression of the cyclin proteins during the cell cycle is shown here.

Schematic structure of cyclins is shown here.

Potential sites for regulation of cdk-cyclin complexes are shown here
(copied from the slide show  in  http//www.sb-roscoff.fr/CyCell/cycleintro.html).

Cyclins and CDK inhibitors that associate with the various CDKs are shown here. (copied from the slide show in: http//www.sb-roscoff.fr/CyCell/cycleintro.html).
