General annotation (Comments)

Function	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 By similarity. Ref.2
Catalytic activity	ATP + H2O = ADP + phosphate.
Subunit structure	Heterodimer of an alpha and a beta subunit.
Subcellular location	Nucleus.
Sequence similarities	Belongs to the TFIIF beta subunit family.
