Regulation of cytokinesis is essential for the cell during its division cycle. Failure to do so can lead to aneuploidy, which can be fatal and lead to senescence or cancer. A useful model organism for studying cytokinesis in eukaryotes is Schizosaccharomyc ...

Premature activation of Cdk1 leads to mitotic events in S phase and embryonic lethality

Patricia Renck Nunes

Cell cycle regulation, especially faithful DNA replication and mitosis, are crucial to maintain genome stability. Cyclin-dependent kinase (CDK)/cyclin complexes drive most processes in cellular proliferation. In response to DNA damage, cell cycle surveilla ...

Physiological regulation of the CDK16/PCTAIRE-1 protein kinase and its proposed role in the brain

Saifeldin Nasser Mohamed Ibrahim Shehata

Cell signalling, mediated to a large extent by protein kinase phosphorylation, plays a vital role in regulation of cellular function. PCTAIRE-1 (also known as cyclin-dependent protein kinase (CDK)16), is a Ser/Thr kinase that has been implicated in many ce ...

Cdk2 strengthens the intra-S checkpoint and counteracts cell cycle exit induced by DNA damage

Gérald Joseph Paul Lossaint, Katarina Bacevic

Although cyclin-dependent kinase 2 (Cdk2) controls the G1/S transition and promotes DNA replication, it is dispensable for cell cycle progression due to redundancy with Cdk1. Yet Cdk2 also has non-redundant functions that can be revealed in certain genetic ...

CDK4 Phosphorylates AMPK alpha 2 to Inhibit Its Activity and Repress Fatty Acid Oxidation

Anita Nasrallah, Caterina Collodet, Judit Castillo Armengol

The roles of CDK4 in the cell cycle have been extensively studied, but less is known about the mechanisms underlying the metabolic regulation by CDK4. Here, we report that CDK4 promotes anaerobic glycolysis and represses fatty acid oxidation in mouse embry ...

Identification of genetic interactors of ypa2 in Schizosaccharomyces pombe

Manuela Moraru

In this study, the fission yeast Schizosaccharomyces pombe was used as a model system to study the cellular signaling that underlies cell cycle progression. Phosphorylation plays an important part in the regulation of this process. Kinases catalyze the tra ...

An Extended, Boolean Model of the Septation Initiation Network in S-pombe Provides Insights into Its Regulation

Viesturs Simanis, Andrea Krapp, Elena Cano, Anastasia Chasapi, Ioannis Xenarios

Cytokinesis in fission yeast is controlled by the Septation Initiation Network (SIN), a protein kinase signaling network using the spindle pole body as scaffold. In order to describe the qualitative behavior of the system and predict unknown mutant behavio ...

Cyclin Y phosphorylation- and 14-3-3-binding-dependent activation of PCTAIRE-1/CDK16

Kei Sakamoto, Maria Deak

PCTAIRE-1 [also known as cyclin-dependent kinase 16 (CDK16)] is implicated in various physiological processes such as neurite outgrowth and vesicle trafficking; however, its molecular regulation and downstream targets are largely unknown. Cyclin Y has rece ...

The Schizosaccharomyces pombe septation initiation network (SIN) regulates cytokinesis, and asymmetric association of SIN proteins with the mitotic spindle pole bodies (SPBs) is important for its regulation. Here, we have used semi-automated image analysis ...

Spindle positioning and spindle elongation are critical for proper cell division. In human cells, an evolutionary conserved ternary complex (NuMA/LGN/Gαi) anchors dynein at the cortex during metaphase, thus ensuring correct spindle positioning. Whether thi ...
