Figure 3From: Investigations into the relationship between feedback loops and functional importance of a signal transduction network based on Boolean network modelingDistribution of proteins with respect to connectivity and the NuFBL. (a) Proteins were classified into "Lethal", "Viable", and "Not obvious", respectively, according to their mutant phenotypes. (b) Proteins were classified into "Slow", "Middle", and "Fast", respectively, according to their evolutionary rates (see additional data file 3 for further details).Back to article page
