AP-1 binding sites are over-represented in promoters of up-regulated targets. Frequencies of promoters containing at least one AP-1 binding site were determined using TFExplorer predicted regulatory element database. Among the genes displayed on the microarray, absent genes were those with undetectable expression in Min6 and present genes were those with detectable expression in Min6. *, p < 0.01 by Fisher exact test vs present genes.
