How the cell cycle is controlled
Nettet5. des. 2014 · The cell cycle is controlled by a number of protein-controlled feedback processes. Two types of proteins involved in the control of the cell cycle are kinases and cyclins. Cyclins activate kinases by binding to them, specifically they activate cyclin-dependent kinases (CDK). Nettet14. apr. 2024 · During root nodule symbiosis (RNS), cell-division activity is re-initiated and sustained in the root cortex to create a hospitable cellular niche. Such temporary and spatially confined site is required to render host cells compatible with the intracellular progression of rhizobia. Although it has been suggested that early infection events …

NettetIn addition to the internally controlled checkpoints, there are two groups of intracellular molecules that regulate the cell cycle. These regulatory molecules either promote progress of the cell to the next phase (positive regulation) or halt the cycle (negative regulation) (Figure 2). NettetThe general answer is that internal and external cues trigger signaling pathways inside the cell that activate, or inactivate, a set of core proteins that move the cell cycle forward. …

Our results unveil an unsuspected implication of Rad53 in the control of Cdk1 activity, and reconcile the long-standing conundrum of Swe1 dispensability. More recently, we identified that even when cells fail to trigger a full DNA damage response,
