Bimodal and monomodal transcription factor occupied loci have a similar genomic distribution. (A) Distributions of distance to the closest transcriptional start site (dTSS) for transcription factor occupied loci within 50 kb of a RefSeq gene TSS. (B) Fractions of bimodal, monomodal, or low H3K4me1 sites in transcriptionally active, inactive, or non-genic regions. (C) Proportion of bimodal, monomodal, or low H3K4me1 sites associated with an expressed (tag count >5), non-expressed (H3K4me3 marks at the promoter, tag count <5), or silenced (no H3K4me3 at the promoter, tag count <5) genes.
