Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including defense response to protozoan; immune system development; and positive regulation of macromolecule metabolic process. Located in cytoplasm and nucleus. Is expressed in bladder and testis. Orthologous to human BATF (basic leucine zipper ATF-like transcription factor). [provided by Alliance of Genome Resources, Apr 2022]
