Phenol Model

Phenol sensor model


Introduction

In this section we model the phenol sensor in Kappa. Kappa is a rule based language allowing the expression of protein-protein interactions in order to build executable models of protein networks. This project is supported by the harvard medical school and can be found in the Kappa homepage. This model is then simulated using KaSim, an open source stochastic simulator for rule-based models written in Kappa. Basically, KaSim takes one or several Kappa files as input and generates stochastic trajectories of various observables. according to literature, the phenol sensor is composed of phosphoriled Dmpr dimers forming hexamers and binding on the P0 site as described in the schemas bellow from David Tropel and Jan Roelof van der Meer researches[1].
