Summary: Enables nuclear receptor activity and steroid hormone receptor activity. Acts upstream of or within regulation of transcription, DNA-templated; response to toxic substance; and transcription by RNA polymerase II. Predicted to be located in nucleus. Is expressed in several structures, including adenohypophyseal placode; brain; heart; liver; and pleuroperitoneal region. Orthologous to human NR1I2 (nuclear receptor subfamily 1 group I member 2).

What's a GeneRIF?

The Pxr variants differed in both their ability to bind these structurally different ligands and to regulate reporter gene expression in vitro. We infer that the observed sequence variations in zebrafish Pxrs likely affect the response to putative Pxr agonists in vivo and potentially cause strain-specific biotransformation of xenobiotics in zebrafish.

Selected zebrafish CYP1, CYP2 and CYP3 genes appear to be under the regulation of both pregnane X receptor and aryl hydrocarbon receptor 2.

CYP3A65 and PXR may be involved in the metabolization and detoxification of microcystins in zebrafish, which may be regulated by dre-miR-27b.
Title: Transcription alterations of microRNAs, cytochrome P4501A1 and 3A65, and AhR and PXR in the liver of zebrafish exposed to crude microcystins.
similar pattern of mRNA expression of PXR, cytochrome P4503A and multiple drug resistance 1 genes found in fish treated with different PXR inducers suggests that the intrinsic association between these three genes is conserved in zebrafish

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
