Splet16. avg. 2024 · Using the mitotic cyclin/cdk complex as an example, the cyclin (cdc13) and cdk (cdc2) come together to form an inactive complex. The cdk is then phosphorylated by wee1, a kinase. The phosphate it puts on tyrosine-15 is needed for the rest of the activation sequence, but it is inhibitory: it actually prevents final activation. Splet15. okt. 2011 · Various cyclin-dependent kinase (Cdk) complexes have been implicated in the regulation of transcription.
