Invitrogen™ PXR (SXR) Ligand Binding Domain Protein, GST Tag Recombinant Protein

Description

Recombinant Protein

Pregnane X Receptor (Steroid and Xenobiotic Receptor), Ligand Binding Domain (PXR (SXR)-LBD) is a 64.7 kDa recombinant human protein (amino acids 111-434) expressed as a GST fusion protein in baculovirus-infected insect cells. PXR (SXR)-LBD was expressed and purified in the absence of exogenous ligands, making it ideal for ligand binding and coregulator recruitment or displacement studies. Protein Form: Recombinant, Ligand Binding Domain

This gene product belongs to the nuclear receptor superfamily, members of which are transcription factors characterized by a ligand-binding domain and a DNA-binding domain. The encoded protein is a transcriptional regulator of the cytochrome P450 gene CYP3A4, binding to the response element of the CYP3A4 promoter as a heterodimer with the 9-cis retinoic acid receptor RXR. It is activated by a range of compounds that induce CYP3A4, including dexamethasone and rifampicin. Several alternatively spliced transcripts encoding different isoforms, some of which use non-AUG translation initiation codon, have been described for this gene. Additional transcript variants exist, however, they have not been fully characterized.
