To faithfully capture this combinatorial process in a math- ematical model is an important challenge in systems biology. Exploiting the limited context on which most binding and modification events are conditioned, attempts have been made to reduce the com- binatorial complexity by quotienting the reachable set of molecular species, into species aggregates while preserving the deterministic semantics of the thermodynamic limit. Recently we proposed a quotienting that also preserves the stochastic semantics and that is complete in the sense that the semantics of individual species can be recovered from the aggregate semantics. In this paper we prove that this quotienting yields a sufficient condition for weak lumpability and that it gives rise to a backward Markov bisimulation between the original and aggregated transition system. We illustrate the framework on a case study of the EGF/insulin receptor crosstalk. https://research-explorer.ista.ac.at/download/3719/5904/Lumpability_abstractions_of_rule-based_systems.pdf application/pdfno Open Publishing Association2010Jena, Germany eng 1011.0496 40142-161 https://research-explorer.ista.ac.at/record/3168 Feret J, Henzinger TA, Koeppl H, Petrov T.
