Binds and transactivates the retinoic acid response elements that control expression of the retinoic acid receptor beta 2 and alcohol dehydrogenase 3 genes. Transactivates both the phenobarbital responsive element module of the human CYP2B6 gene and the CYP3A4 xenobiotic response element. Interacts with ECT2. Heterodimer of NR1I3 and RXR. Interacts with PSMC4. Directly interacts with DNAJC7. The DNAJC7-NR1I3 complex may also include HSP90. By dexamethasone. Predominantly expressed in liver. Belongs to the nuclear hormone receptor family. NR1 subfamily. 7 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
