GTF2F2, also known as 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. This subunit shows ATP-dependent DNA-helicase activity. Source: Recombinant protein corresponding to aa1-249 of human GTF2F2, fused to His-tag at N-terminal expressed in E. coli.
