Trans-acting factors can be categorized by their interactions with the regulated genes, cis-acting elements of the genes, or the gene products. DNA binding trans-acting factors regulate gene expression by interfering with the gene itself or cis-acting elements of the gene, which lead to changes in transcription activities.
