Webb23 dec. 2024 · Phosphorylation of APC/C subunits by Cyclin B/CDK1 complex triggers APC/C CDC20 activity [ 28] which is required to promote the metaphase to anaphase transition. Major substrates of APC/C CDC20 are NEK2A, Cyclin A, Cyclin B, and Securin. Webb25 apr. 2013 · CDK activation minimally depends on two events: binding to a cyclin and phosphorylation of a conserved Thr residue in the activation (T) loop. Cyclins are expressed at different times in response to extracellular, mitogenic signals or internal, cell-autonomous cues.

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. But once Tyr-15 is phosphorylated, CAK can phosphorylate a neighboring threonine (Thr-161), which is required for activation.

Here, we have tested the hypothesis that DNA replication determines the timing ... WebbRecent studies have shown that autophagy initiation is repressed, and cap-dependent mRNA translation is maintained during mitosis despite mTORC1 activity being repressed. This is achieved in large part by a switch from mTORC1- to cyclin-dependent kinase 1 (CDK1)-mediated regulation. Here, we review the history and recent advances and seek …

Webb25 maj 2024 · Cdk1 is phosphorylated at T161, triggering a refolding of the active site cleft that allows the enzyme to bind substrates. At the same time, a double phosphorylation of Cdk1, at Y15 and T14, achieved by two partly redundant kinases, Wee1 and Myt1, maintains the Cdk1-Cyclin B complex under an inactive state, known as pre-MPF. Fig. 1 WebbEMBO Journal. July 21, 2010. The balance between cell cycle progression and apoptosis is important for both surveillance against genomic defects and responses to drugs that arrest the cell cycle. In this report, we show that the level of the human anti-apoptotic protein Mcl-1 is regulated during the cell cycle and peaks at mitosis.
