Figure 5.
Profiles of factors on genes with different spatial–temporal expression. Average signal profiles in the 2 kb around transcript start sites (TSS) and transcript termination sites (TTS) are shown for selected factors on four categories of genes: ubiquitously expressed genes, silent genes (genes encoding serpentine receptors), genes expressed specifically in somatic tissues, and genes expressed specifically in the maternal adult germline. The top two rows are marks associated with active gene expression; the bottom two rows are marks associated with repression.
