Predicted to enable several functions, including RNA polymerase II core promoter sequence-specific DNA binding activity; RNA polymerase II general transcription initiation factor activity; and TBP-class protein binding activity. Predicted to be involved in transcription by RNA polymerase II. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of transcription factor TFIIA complex; transcription factor TFIID complex; and transcription preinitiation complex. Orthologous to human GTF2A1 (general transcription factor IIA subunit 1). [provided by Alliance of Genome Resources, Apr 2022]
