Abstract

Boolean networks are discrete dynamical systems for modeling regulation and signaling in living cells. We investigate a particular class of Boolean functions with inhibiting inputs exerting a veto (forced zero) on the output. We give analytical expressions for the sensitivity of these functions and provide evidence for their role in natural systems. In an intracellular signal transduction network [Helikar, Proc. Natl. Acad. Sci. USA 105, 1913 (2008)PNASA60027-842410.1073/pnas.0705088105], the functions with veto are over-represented by a factor exceeding the over-representation of threshold functions and canalyzing functions in the same system. In Boolean networks for control of the yeast cell cycle [Li, Proc. Natl. Acad. Sci. USA 101, 4781 (2004)PNASA60027-842410.1073/pnas.0305937101; Davidich, PLoS ONE 3, e1672 (2008)1932-620310.1371/journal.pone.0001672], no or minimal changes to the wiring diagrams are necessary to formulate their dynamics in terms of the veto functions introduced here.
