While Ro-VDR cells showed typical nuclear localization of the unoccupied 1,25(OH)2D3 receptor , neither the unoccupied nor the occupied receptor from A1-VDR cells was completely localized in the nucleus .
 protein: receptor; protein: unoccupied 1,25(OH)2D3 receptor; cell line: A1-VDR cells; protein: receptor; cell line: Ro-VDR; cell line: Ro-VDR cells; cell line: A1-VDR
