cREMaG is a database interface allowing for detection of the over-representation of transcription factor binding sites (TFBS) for a queried set of co-expressed genes. If the genes are co-expressed it is highly probable that they are co-regulated. Analysis of common properties of their promoters could suggest the transcription factors responsible for their corregulation.
