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 negative regulation of viral transcription and positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within angiogenesis. Predicted to be located in cytosol and nucleoplasm. Predicted to be active in nucleus. Orthologous to human UBP1 (upstream binding protein 1). [provided by Alliance of Genome Resources, Apr 2022]
