Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in NK T cell proliferation; natural killer cell proliferation; and positive regulation of transcription by RNA polymerase II. Predicted to be located in PML body. Predicted to be active in nucleus. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and sensory organ. Orthologous to human ELF4 (E74 like ETS transcription factor 4). [provided by Alliance of Genome Resources, Apr 2022]
