Transcription patterns of additional clock-controlled TFs. (a) Expression profiles of each TF in the homeostatic rat liver; the horizontal axis is the zeitgeber time (hr) and the vertical axis is the z-score normalized expression levels. Error bars are two standard deviations of expression values at each particular time-point. (b) The temporal organization of clock-controlled TFs. TFs with similar binding sites are combined into a TF family in the computational context. They are arranged following their corresponding peak circadian times.
