The study described here was undertaken to extend the observation that some transcription factors can either stimulate or suppress gene expression depending on the local environment of their DNA binding site. It is suggested that if such transcription factors also had a mechanism to sense the expression level of the gene they control, then they could create a feedback loop able to keep expression of a gene within a limited range. The transcription factor would be activating if gene expression were determined to be too low and repre
