Classification of genes according to ChIP data and inferred regulatory coupling. The number of genes in each of the categories (B-, unbound genes; B+/C+, bound and coupling genes; B+/C+, genes that are bound but do not couple) is shown for each of the 37 transcription factors analyzed. On average, 58% of the significantly bound genes were classified in the B+/C+ group.
