Dynamic model of the transcriptional regulatory system of a target gene. The candidate regulatory TFs of the target gene were obtained from the genome-wide TF binding location data by chromatin immunoprecipitation [10,11]. A binding transcription factor p has a regulatory ability α p and interactivities with TF q to produce the regulatory ability βp, q. The microarray data for these TFs provide the inputs X p (t) of the transcriptional regulatory system and produce the output Y (t) of the target gene.
