title: Cloning of a human gene encoding the general transcription initiation factor IIB.
abstract: Transcription factor IIB (TFIIB) has a central role in transcription of class II genes. The purification of the human TFIIB protein and isolation of a complementary DNA encoding TFIIB activity is reported here. The sequence of TFIIB, which seems to be encoded by a single gene, contains a repeated motif, in addition to a motif with similarity to the prokaryotic sigma-factors. The recombinant protein expressed in bacteria substituted for all the functions attributed to the human TFIIB protein.
