Predicted to enable several functions, including AF-2 domain binding activity; DNA-binding transcription factor activity, RNA polymerase II-specific; and identical protein binding activity. Predicted to be involved in positive regulation of cold-induced thermogenesis and positive regulation of transcription by RNA polymerase II. Predicted to be located in nucleus. Orthologous to human ESRRG (estrogen related receptor gamma). [provided by Alliance of Genome Resources, Apr 2022]
