Functional analysis of the Ras signaling network according to 15 cellular processes. Functional enrichment with respect to a reference set of 19,300 proteins. The ‘*’ symbols indicate statistical significance at 0.05 of the respective Fisher’s exact test. The protein percentages were obtained for each class by summing up the proteins after dividing by the number of effector classes each protein is involved in and normalizing by the class-specific sum, as explained in the main text
