Modeling a Minimal CDK Network

Modeling a Minimal CDK Network

This paper reports a computational analysis of the minimal CDK network engineered in fission yeast (doi:10.1038/nature09543). It had been observed that a Cdk-inhibitory mechanism working through tyrosine phosphorylation of the kinase subunit, which is essential for modern fission yeast, is dispensable...

Minimal Cell Cycle

Minimal Cell Cycle

This is a great example of a paper where synthetic biology meets systems biology. The authors developed a minimal cell cycle regulatory network by engineering a synthetic CDK. To simplify the cell cycle control machinery, a cassette expressing a fusion of cdc13 and cdc2under...

Testing of a New Integrated Model of the Yeast START Transition

Testing of a New Integrated Model of the Yeast START Transition

We propose a new model of the yeast start transition. We tested the accuracy of the model by simulating various mutants not described in the literature. The cell cycle is composed of bistable molecular switches that govern the transitions between...

Measurement and modeling of transcriptional noise in the cell cycle regulatory network

Measurement and modeling of transcriptional noise in the cell cycle regulatory network

Fifty years of genetic and molecular experiments have revealed a wealth of molecular interactions involved in the control of cell division. In light of the complexity of this control system, mathematical modeling has proved useful in analyzing biochemical hypotheses that...

Stochastic exit from mitosis in budding yeast: model predictions and experimental observations

Stochastic exit from mitosis in budding yeast: model predictions and experimental observations

Unlike many mutants that are completely viable or inviable, the CLB2-dbΔ clb5Δ mutant of Saccharomyces cerevisiae is inviable in glucose but partially viable on slower growth media such as raffinose. On raffinose, the mutant cells can bud and divide but...

Oscillatory dynamics of cell cycle proteins in single yeast cells analyzed by imaging cytometry

Oscillatory dynamics of cell cycle proteins in single yeast cells analyzed by imaging cytometry

Progression through the cell division cycle is orchestrated by a complex network of interacting genes and proteins. Some of these proteins are known to fluctuate periodically during the cell cycle, but a systematic study of the fluctuations of a broad...
