About NR1I2

Cytogenetic location: 3q13.33 Genomic coordinates (GRCh38): 3:119,782,101-119,818,487 (from NCBI)

This gene has 5 transcripts (splice variants), 340 orthologues and 18 paralogues. Biased expression in small intestine (RPKM 14.5), duodenum (RPKM 13.0) and 4 other tissues.

Summary

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 (CUG) translation initiation codon, have been described for this gene. Additional transcript variants exist, however, they have not been fully characterized. [provided by RefSeq, Jul 2008]
