Fig. 3From: Negative selection maintains transcription factor binding motifs in human cancerTranscription factor binding motifs protected from somatic mutations in different cancer types. The size of a pie shows the total number of motifs in a given transcription factor family (given in curly braces according to TFClass). The slices of a pie show the number of conserved binding motifs protected from any affinity change (yellow), motifs protected from affinity loss (magenta), and motifs protected from affinity gain (deep purple)Back to article page
