Widely present TFs*

All targets
6.7 ± 8.9
13.9 ± 23.5
66.6 ± 85.2
Repressed targets
1.4 ± 2.6
6.2 ± 11.5
16.6 ± 17.8
Activated targets
5.1 ± 9
6.7 ± 12.8
42.3 ± 62.2

*The large standard deviations are due to several global TFs that regulate hundreds of targets. Total targets, including repressed targets, activated targets anddually regulated targets.
