Background: Fission yeast cells growth up to a given size and then enters mitosis. The question this project addresses is how does the cell knows it has reached to right size for division. This is achieved by a gradient of the pom1 protein along the cortex.
Goal: The goal is to mathematically describe the mechanism by which such a gradient is achieved using differential equation and analyze such gradients from fluorescence microscopy images.
Mathematical tools: Ordinary differential equations, Mathematica, Matlab
Biological or Medical aspects: Pom1 is a protein which forms a cortical intracellular gradient that permits to control the entry of mitosis of the fission yeast, S. Pombe. The fact is, interaction of pom1 and cdr2 induces a cell cycle delay following to a gene activation cascade. Microtubuls performs
