Abstract: A major challenge for systems biology is to deduce 
the molecular interactions that underlie correlations
 observed between concentrations of different intracellular molecules.
While direct explanations such 
as coupled transcription or direct protein-protein 
interactions are often considered, potential indirect
 sources of coupling have received much less attention.

In this talk, I will report on an investigation,
 involving both a stochastic model and related experiments,
 of how correlations can arise generically from
 such an indirect coupling
mechanism involving the
 processing of multiple protein species by a common
