Expression levels of PXR in certain metabolic disorders including cancer are reported to be altered and its induced expression is associated with the development of resistance towards chemotherapy and adverse drug-drug interactions. Though the transcriptional regulation of PXR target genes have been elucidated in significant details, the structure and functional control of PXR promoter itself remains inadequately explored. In this work, we identify a Composite Element (CE) located within the proximal PXR promoter region that consists of multiple overlapping cis-elements and demonstrated that CE interacts specifically with some critical nuclear proteins. Subsequent DNA-protein interaction studies revealed mutually exclusive interactions on CE occurring between Sp1 and two unidentified DNA binding proteins with molecular masses of 50 and 54kDa. Here, we report the identification of 54kDa CE binding protein as a heterogeneous nuclear ribonucleoprotein K (hnRNPK) and demonstrate the effect of hnRNP K and Sp1 on PXR promoter transcriptional activity. Overall, the study indicates that PXR gene is tightly regulated to maintain a low receptor level."xsd:string |
