The B type cyclins, B1 and B2, associate with p34cdc2 and are essential components of the cell cycle regulatory machinery. B1 and B2 differ in their subcellular localization. Cyclin B1 co localizes with microtubules, whereas cyclin B2 is primarily associated with the Golgi region.

Unreferenced stub auto yes date December 2009 A cyclin dependent kinase complex abbreviated cdkc , also called cyclin CDK is a protein complex formed by the association of cyclin with cyclin dependent kinase . These complexes are able to phosphorylate other compounds under consumption of Adenosine triphosphate ATP , and are thereby involved in the regulation of the cell cycle . Depending on the type of cyclin attached to CDK, it has a different function. These serve as markers in each phase which are integral for the correct sequence of events, as well as facilitating the transition to the next phase. Classes Image Cyclinexpression waehrend Zellzyklus.png thumb 422px Expression of cyclins through the cell cycle . There are three classes of cdkc depending on the phase of the cell cycle.
