WebABSTRACT. The mammalian G 1-S phase transition is controlled by the opposing forces of cyclin-dependent kinases (CDK) and the retinoblastoma protein (pRB).Here, we present evidence for systems-level control of cell cycle arrest by pRB-E2F and p27-CDK regulation. By introducing a point mutant allele of pRB that is defective for E2F repression (Rb1 G) … WebAug 18, 2024 · Plant Cell Cycle Kinases / The Ins And Outs Of The Plant Cell Cycle Nature Reviews Molecular Cell Biology / The core control system of the cell cycle..

Previous studies have shown that the expression level of mitochondrial creatine kinase 1 (CKMT1) is abnormal in NSCLC, but the mechanism of its effect remains unclear. Therefore, in this study, we intend to clarify the potential …
WebJun 30, 2014 · Cyclin-dependent kinases (CDKs) are protein kinases characterized by needing a separate subunit - a cyclin - that provides domains essential for enzymatic activity. CDKs play important roles in the control of cell division and modulate transcription in response to several extra- and intracellular cues. http://www.cureffi.org/2013/04/06/cell-biology-08-cell-cycle-regulation-and-checkpoints/
