Figure 5. Correlation patterns for interacting proteins measured by the Pearson coefficient ρ as a function of the mean target level.

(A) Case of non-interacting proteins translated from competing transcripts ( and ). (B) Case of interacting proteins translated from post-transcriptionally unregulated transcripts (). (C) Case of interacting proteins translated from competing transcripts ( and ). Lines (blue and orange) correspond to analytical results obtained by the Linear Noise Approximation (see Methods), markers (black and purple) to results from stochastic simulations by the Gillespie algorithm.
