Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within regulation of DNA-templated transcription. Predicted to be located in intracellular membrane-bounded organelle. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 67. Orthologous to human CUX2 (cut like homeobox 2).
