Predicted to enable RNA polymerase II core promoter sequence-specific DNA binding activity and RNA polymerase II general transcription initiation factor activity. Predicted to be involved in DNA-templated transcription, initiation. Predicted to act upstream of or within acrosome assembly; dTTP biosynthetic process; and spermatid nucleus differentiation. Predicted to be located in cytoplasm and nucleus. Predicted to be part of transcription factor TFIIA complex. Orthologous to human TBPL1 (TATA-box binding protein like 1).
