TFIIF is a general transcription initiation factor that binds to RNA polymerase II and helps to recruit it to the initiation complex in collaboration with TFIIB. It promotes transcription elongation. Heterodimer of an alpha and a beta subunit. Interacts with GTF2F2, CTDP1, TAF6/TAFII80 and URI1. Up-regulated in response to enterovirus 71 (EV71) infection. Belongs to the TFIIF alpha subunit family. Note: This description may include information from UniProtKB.
