CncC and Maf regulate the expression of CYP321B1 by binding to a specific site present in the region between −258 to −1 bp. A Schematic representation of the CYP321B1 promoter truncations. B Analysis of CYP321B1 promoter truncations. The cells were harvested at 48 h after transfection and the luciferase activity was quantified. Significant differences in the luciferase activity were identified using Student’s t-test and are indicated using an asterisk. A value of p < 0.05 was considered statistically significant
