General annotation (Comments)

Function

TFIIF is a general transcription initiation factor that binds to RNA polymerase II. Its functions include the recruitment of RNA polymerase II to the promoter bound DNA-TBP-TFIIB complex, decreasing the affinity of RNA polymerase II for non-specific DNA, allowing for the subsequent recruitment of TFIIE and TFIIH, and facilitating RNA polymerase II elongation. TFG2 shows ATP-dependent DNA-helicase activity By similarity.

Catalytic activity

ATP + H2O = ADP + phosphate.

Subunit structure

TFIIF is composed of three different subunits: TFG1/RAP74, TFG2/RAP30 and TAF14.

Subcellular location

Nucleus.

Miscellaneous

Present with 520 molecules/cell in log phase SD medium.

Sequence similarities

Belongs to the TFIIF beta subunit family.
