| Numerical solutions of reaction-diffusion partial differential equations are obtained for modeling protein concentrations, taking into account the physical structure of biological cells. An Immersed Interface Method is used for the numerical solution. The biochemical model is the HOG pathway signaling cascade in Saccharomyces cerevisiae, effectively modeling both time and three dimensional space. Perturbations to the reaction rates in the biochem¬ical system are investigated, along with their corresponding effects regarding the spatial distribution of proteins. A model elucidating the relationship between the Hogl and Rck2 proteins is analyzed and discussed. |
