minimum number of mechanisms that any regulatory network must include, a stress-induced activation and a feedback regulation,
and can thus be regarded as the archetype for a cellular regulatory process. We propose here a simple mechanistic model for
the eukaryotic heat shock response, including its mathematical validation. Based on numerical predictions of the model and
on its sensitivity analysis, we minimize the model by identifying the reactions with marginal contribution to the heat shock
response. As the heat shock response is a very basic and conserved regulatory network, our analysis of the network provides
a useful foundation for modeling strategies of more complex cellular processes.
