None.

Family relationships

None.

Description

Accurate transcription in vivo requires at least six general transcription initiation factors, in addition to RNA polymerase II. Transcription initiation factor IIF (TFIIF) is a tetramer consisting of two large subunits (TFIIF alpha or RAP74) and two small subunits (TFIIF beta or RAP30) [PMID: 7596813]. The beta subunit of TFIIF is required for recruitment of RNA polymerase II onto the promoter.
