A method for identifying transcriptional regulatory proteins that modulate the transcription of a gene of interest is disclosed. In one embodiment, the method comprises introducing into a cell a nucleic acid molecule comprising three central components: 1) a polynucleotide (<i>e.g.</i>, DNA) encoding a transcriptional regulatory protein; 2) an indicator gene which is responsive to, <i>e.g.</i>, under the transcriptional control of, the gene regulatory sequences of a gene of interest which bind to the transcriptional regulatory protein; and 3) a selectable marker gene. The transcriptional regulatory protein binds to the gene regulatory sequences and either activates or inhibits transcription. A protein is identified as a modulator of the transcription of the gene of interest by detecting a signal generated by the indicator gene.
