Predicted to enable DNA binding activity; identical protein binding activity; and promoter-specific chromatin binding activity. Predicted to contribute to RNA polymerase II general transcription initiation factor activity. Predicted to be involved in transcription initiation from RNA polymerase II promoter. Predicted to be located in actin cytoskeleton; chromatin; and nucleoplasm. Predicted to be part of transcription factor TFIID complex and transcription factor TFTC complex. Orthologous to human TAF5 (TATA-box binding protein associated factor 5). [provided by Alliance of Genome Resources, Apr 2022]
