Predicted to enable several functions, including P-TEFb complex binding activity; TFIIH-class transcription factor complex binding activity; and nuclear receptor binding activity. Predicted to contribute to H3K27me3 modified histone binding activity and RNA polymerase II general transcription initiation factor activity. Predicted to be involved in RNA polymerase II preinitiation complex assembly; negative regulation of macromolecule metabolic process; and positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within intracellular estrogen receptor signaling pathway and transcription by RNA polymerase II. Predicted to be located in cytoplasm and nucleus. Predicted to be part of MLL1 complex; transcription factor TFIID complex; and transcription factor TFTC complex. Orthologous to human TAF7 (TATA-box binding protein associated factor 7).
