Mathematical Model of a Protein-Protein Interaction Network

Abstract

A spatial-temporal model of theoretical protein-protein interactions is developed to analyze the behavior of a network of proteins that exist in two states: active and inactive. After given an initial protein concentration, the proteins activate and inactivate proteins in the network. After the proteins interact with each other, the concentrations of the proteins reach a unique steady state. This model mathematically explains how a network of proteins generates a specific protein concentration.
