Enables DNA-binding transcription factor activity; identical protein binding activity; and sequence-specific DNA binding activity. Involved in several processes, including neuron apoptotic process; regulation of gene expression; and response to peptide hormone. Located in PML body; cytoplasm; and dendrite. Human ortholog(s) of this gene implicated in lung small cell carcinoma and pheochromocytoma. Orthologous to human MAX (MYC associated factor X). [provided by Alliance of Genome Resources, Apr 2022]
