Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and retinoid X receptor binding activity. Contributes to sequence-specific DNA binding activity. Involved in regulation of gene expression; response to nutrient levels; and retinoic acid receptor signaling pathway. Predicted to be located in cytoplasm and nucleus. Biomarker of obesity. Human ortholog(s) of this gene implicated in obesity and type 2 diabetes mellitus. Orthologous to human NR1H2 (nuclear receptor subfamily 1 group H member 2). [provided by Alliance of Genome Resources, Apr 2022]
