Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-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 positive regulation of transcription by RNA polymerase II and spermatogenesis. Predicted to be located in several cellular components, including Golgi apparatus; mitochondrion; and nucleus. Predicted to be active in nucleus. Orthologous to human CREB3L4 (cAMP responsive element binding protein 3 like 4). [provided by Alliance of Genome Resources, Apr 2022]
