Positive predictive value curves for 15 developmental/hormone response TFs, as a function of the number of TFBS being predicted. See caption of Figure 2 for details. In some cases (e.g. NF-E2, MEF2A, EBF), very few binding loci were identified by our algorithm, resulting in the impossibility of that approach to make more than a handful of TFBS predictions, explaining why the green curve does not extend over the full range of the x axis.
