Predicted to enable protein C-terminus binding activity; transcription coactivator activity; and transcription corepressor activity. Predicted to be involved in positive regulation of transcription by RNA polymerase II and regulation of transcription involved in G1/S transition of mitotic cell cycle. Predicted to act upstream of or within in utero embryonic development. Predicted to be located in Cajal body; Gemini of coiled bodies; and cytoplasm. Predicted to be active in nucleus. Orthologous to human NPAT (nuclear protein, coactivator of histone transcription). [provided by Alliance of Genome Resources, Apr 2022]
