Transcriptional regulatory networks and the yeast cell cycle

A large amount of microarray gene expression data relevant to the yeast cell cycle has been collected, and several hundred genes have been placed into a model transcriptional control network. Genome-wide studies of the location of cell cycle transcription factors, and a variety of computational approaches, have allowed refinement of the model, and at the same time show how other genome-wide data sets may be organised into model networks.
