Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific; double-stranded DNA binding activity; and lipopolysaccharide binding activity. Predicted to act upstream of or within detection of lipopolysaccharide; non-canonical inflammasome complex assembly; and positive regulation of transcription by RNA polymerase II. Predicted to be located in several cellular components, including chromatin; cytosol; and mitochondrion. Orthologous to human NR4A1 (nuclear receptor subfamily 4 group A member 1).
