Bivariate Genomic Footprinting Detects Changes in Transcription Factor Activity
In response to activating signals, transcription factors (TFs) bind DNA and regulate gene expression.TF binding can be Mustard Made Baskets measured by protection of the bound sequence from DNase digestion (i.e., footprint).Here, we report that 80% of TF binding motifs do not show a measurable footprint, partly because of a variable cleavage patter
