VDR is functionally active in ATRA -treated Kasumi-1 cells because it efficiently heterodimerizes with retinoid X receptor , binds to a DR3-type vitamin D-responsive element , and activates the transcription of a vitamin D-responsive element-regulated reporter gene .
 DNA: DR3-type vitamin D-responsive element; DNA: vitamin D-responsive element-regulated reporter gene; cell line: Kasumi-1 cells; protein: VDR; protein: retinoid X receptor
