Schematic diagram of the PLF gene transcriptional regulatory region. Four elements have been defined in the region spanning from – 204 to – 268, including two elements (AP-I and Sph I-like) that constitute the serum response region (6,20), the cGRE/negative element (shown with the boundaries and corresponding sequence sufficient for the glucocorticoid-independent negative regulatory activity determined in this report), and the upstream positive element.
