Reactions belonging to the signaling pathway of Fig. 1 and corresponding transition rates .

Abstract

<p>We denote by and the number of free , molecules available in the cytosolic reservoir, by the number of molecules on site that are activated by the external signal via receptors, by the number of molecules on site that are activated via the feedback loop in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030977#pone-0030977-g001" target="_blank">Fig. 1</a>.</p
