Cyclin A is the ONLY cyclin that plays a role in regulation of two cell cycle stages. It can activate two CDKs – CDK2 and CDK1. When Cyclin A forms a complex with CDK2, it allows the cell to progress to S phase. Meanwhile, binding of Cyclin A to CDK1 allows entry into M phase...
DNA replication and mitosis are dependent on the activity of cyclin-dependent protein kinase(CDK) enzymes, which are heterodimers of a catalytic subunit with a cyclin subunit. Cyclinbinding to specific individual proteins is thought to provide potential substrates to Cdk. Protein binding by cyclins is...
Assembly of protein complexes with cyclin/Cdk is noted and the capacity of the cyclin-dependent kinase subunit Cks, in such complex, to extend the range of Cdk substrates is documented and discussed in terms of cell cycle regulation. Cell cycle progression involves changing abundance of individual...
How does the cyclinCDKcomplex regulate the cell cycle? Explain. Cell Cycle: A cell cycle is an important event through which the division of cells takes place. It takes place in four-phase such as G1, S, G2, and M phases. It consists of two main stages interphase and mitotic stage....
所有的Cyclin在N端都具有同源的破坏框,可被后期促进复合物(anaphase promoting complex/cyclosome, APC/C)泛素化降解。由于Cyclin在细胞分裂过程中会出现周期性的表达和降解,而CDK必须在结合Cyclin的情况下才能发挥激酶的作用,MPF的活性会呈...
The dominant model for eukaryotic cell cycle control proposes that cell cycle progression is driven by a succession of CDK complexes with different substrate specificities. However, in fission yeast it has been shown that a single CDK complex generated by the fusion of the Cdc13 cyclin with the ...
Cyclin D1 and its catalytic partner CDK4 are known to play important roles in the G1/S checkpoint of the cell cycle. The complex formed by CDK4 and cyclin D1 has been strongly implicated in the control of cell proliferation and prognoses in human malignancies. We investigated the immunohisto...

Formation and activation of a cyclin E-cdk2 complex during the G1 phase of the human cell cycle The major cyclin E-associated kinase in human cells was Cdk2 (cyclin-dependent kinase 2). The abundance of the cyclin E protein and the cyclin E-Cdk... A Koff,A Giordano,D Desai,... -...
The transcription factor, the Cdk, its cyclin and their regulator: directing the transcriptional response to a nutritional signal. The Pho80-Pho85 cyclin-cdk complex prevents transcription of PHO5 by inhibiting the ability of the basic-helix-loop-helix transcription factor Pho4 to acti... K Hirs...
