Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; identical protein binding activity; and nuclear receptor activity. Acts upstream of or within positive regulation of transcription from RNA polymerase II promoter involved in cellular response to chemical stimulus and retinoic acid receptor signaling pathway. Predicted to be located in nucleus. Predicted to be part of RNA polymerase II transcription regulator complex. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; musculature; and sensory organ. Human ortholog(s) of this gene implicated in lung non-small cell carcinoma. Orthologous to human RXRG (retinoid X receptor gamma). [provided by Alliance of Genome Resources, Apr 2022]
