Figure 2From: Different distribution of histone modifications in genes with unidirectional and bidirectional transcription and a role of CTCF and cohesin in directing transcriptionOverlap between active genes and gene annotations across cell lines. (A) All protein-coding genes (n = 19,950) were subdivided based on the number of cell lines in which they were active (between 0 and 6). (B) Protein-coding genes active in at least two cell lines were divided into three groups: unidirectional in all cell lines ‘Uni’, differently annotated ‘Mixed’, and bidirectional in all cell lines ‘Bi’.Back to article page
