  We study kinetic model of Nuclear Receptor Binding to Promoter Regions. This
model is written as a system of ordinary differential equations. Model
reduction techniques have been used to simplify chemical kinetics.In this case
study, the technique of Pseudo-first order approximation is applied to simplify
the reaction rates. CellDesigner has been used to draw the structures of
chemical reactions of Nuclear Receptor Binding to Promoter Regions. After model
reduction, the general analytical solution for reduced model is given and the
number of species and reactions are reduced from 9 species and 6 reactions to 6
species and 5 reactions.
