Enables nuclear receptor activity. Predicted to be involved in several processes, including regulation of transcription by RNA polymerase II; xenobiotic catabolic process; and xenobiotic transport. Predicted to act upstream of or within negative regulation of transcription, DNA-templated and positive regulation of gene expression. Located 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, Apr 2022]
