TFBS data on the Promoterome Matrix (P-matrix). (A) Histogram of the number of TFBSs in the promoter region of 9,242 bovine genes; (B) Distribution of the number of common TFBSs in the promoter regions of all gene pairs; (C) Log-log plot of the distribution of TFs as a function of the number of predicted TGs; (D) Number of partners as a function of the number of common TGs for each TF. The best fits for a non-linear growth curve are indicated (i.e. with TF having at least one TG and yielding an R² of 94%) or forcing the {0,0} co-ordinate (i.e. zero partners if zero TGs and yielding an R² of 85%).
