Blimp-1 position weight matrix. (A) Position weight matrix used in this study, which was taken from the reported binding sequences in Kuo and Calame (2004). (B and C) Enrichment analysis of known tracheal genes among genes predicted to be regulated by Blimp-1. P-values and ORs are shown for Fisher tests with varying Matscan scores for the definition of predicted binding sites. For values <85, ORs are relatively constant and >1.5 (associated P-values <0.05, dashed line) showing robustness against variations of the Matscan parameter.
