Summary: Enables nuclear receptor activity. Predicted to be involved in several processes, including cellular response to type I interferon; regulation of transcription by RNA polymerase II; and xenobiotic transport. Predicted to act upstream of or within negative regulation of DNA-templated transcription and positive regulation of gene expression. Predicted to be located in intermediate filament cytoskeleton and nuclear body. Predicted to be part of transcription regulator complex. Predicted to be active in nucleus. Biomarker of cholestasis and epilepsy. Orthologous to human NR1I2 (nuclear receptor subfamily 1 group I member 2). [provided by Alliance of Genome Resources, Dec 2024]

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.
