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, None) , ( DNA: vitamin D-responsive element-regulated reporter gene, None) , ( cell line: Kasumi-1 cells, None) , ( protein: VDR, None) , ( protein: retinoid X receptor, None)
