it is important, that the cyclins are changed during the cycle, that is, for each phase, you need another cyclin. If it wasn't degraded, the cell would be arrested.

Cell Cycle

... kinases (CDKs). These enzymes (in budding yeast there is actually only one, propably also in the fission yeast S.pombe) are regulated by cyclins (http://en.wikipedia.org/wiki/Cyclin). Different cyclin variants are only expressed during different cell cycle phases to enable the activation ...

Proteins in Mitosos and the Cell Cycle :)

... phase cyclin/CDK, then it is marked for UbQ by SCF. With APC/C, a protein called Cdh1 is attached to the ACTIVE APC/C that ubiquinates mitotic cyclins. When G1 cylin-CDKs are expressed then Cdh1 becomes phosphorylated by them and the Cdh1 then releases the APC/C, making it inactivated. As far ...
