"cell cycle control mechanism: mainly involved 2 components, cyclin- dependent protein kinases(CdKs) major component of cell cycle control mechanism. mechanism that helpthe cell to have a properly timed cell cycle and coordination of cell cycle various events. cdks depend on the cyclin subunit. it is a complex formed between cdks and cyclin, oscillations happen between these 2 ccomplexes responsible for the control of the cell cycle. s cyclin cdk complex, m cyclin cdk complexes. APC/C enzyme for cell cycle control mechanim also called anaphase promoting complex. SCF ubiquitinase important for cell cycle control mechanism. mechanism involved in cell cycle control. 1. phosphorylation of CDKs 2. proteolysis of cyclins 3. binding of the cdk inhibitor proteins: CKIs 4. changes in the transcript of genes that code for the regulatory protein
