Experimental Process

DNAse footprint to identify site, beta-gal to validate regulation some site directed mutagenesis with EMSA to confirm binding

Transcription Factor Binding Sites

Gene Regulation

Regulated genes for each binding site are displayed below. Gene regulation diagrams show binding sites, positively-regulated genes, negatively-regulated genes, both positively and negatively regulated genes, genes with unspecified type of regulation. For each indvidual site, experimental techniques used to determine the site are also given.
