Phosphatase specificity influences phosphorylation timing of CDK substrates during the cell cycle
Cell cycle events are ordered by cyclin-dependent kinases (CDKs), which phosphorylate hundreds of substrates. Multiple phosphatases oppose these CDK substrates, yet their collective role in regulating phosphorylation timing in vivo remains unclear. Here,

Background The histone code, comprised of diverse histone post-translational modifications, intricately regulates nucleosome organization and gene expression. Histone marks also serve as binding sites for a diverse array of protein complexes and enzymes,

Drosophila researchers met in sunny San Diego for the 49th annual meeting of The Genetics Society of America. It was cold outside and even colder inside. Like last year, ‘Mitosis, Meiosis and Cell Division’ was no longer a session. Instead, we searched out and covered talks and posters in ‘Cell Division and Growth Control’, ‘Gametogenesis ...

CDK activity at the centrosome regulates the cell cycle
Summary: In human cells and yeast, an intact “hydrophobic patch” substrate docking site is needed for mitotic cyclin centrosomal localization. A hydrophobic patch mutant (HPM) of the fission yeast mitotic cyclin Cdc13 cannot enter mitosis, but whether ...

Deconstructing the cell cycle [PDF]
When I was an undergraduate student, knowing three key concepts would ensure success in 'Cell Cycle 101': that oscillations of cyclin–cyclin dependent kinase (CDK) complexes drive the cell cycle; that directionality is ensured by the irreversibility of periodic proteasome-mediated cyclin degradation; and that checkpoints ensure the dependence of later ...

CDK control pathways integrate cell size and ploidy information to control cell division
Maintenance of cell size homeostasis is a property that is conserved throughout eukaryotes. Cell size homeostasis is brought about by the co-ordination of cell division with cell growth and requires restriction of smaller cells from undergoing mitosis ...

Capturing CDKs in action: Live-cell biosensors pioneer the new frontiers in cell cycle research
Cyclin-dependent kinases (CDKs) orchestrate cell cycle progression through precise temporal control of substrate phosphorylation. While traditional biochemical approaches and phosphoproteomics have provided valuable insights into CDK-mediated regulation,

Tumor suppressor p53 is a major cellular guardian of genome integrity, and its inactivation is the most frequent genetic alteration in cancer, rising up to 80% in squamous cell carcinoma (SCC).

In multicellular organisms, cell proliferation and death must be regulated to maintain tissue homeostasis. Many observations suggest that this regulation may be achieved, in part, by coupling the process of cell cycle progression and programmed cell death by using and controlling a shared set of factors.

Cell cycle proteins: Linking the cell cycle to tumors
The cell cycle is a tightly coupled series of events that enable cells to grow and proliferate. Cyclin-dependent kinases (CDKs) play crucial roles in the cell cycle by enabling cells to transition between different phases when they are activated. Cell cycle proteins enhance the activity of CDKs, while natural CDK inhibitors (CDKIs) suppress them.
