TAF6 C-terminal HEAT repeat (IPR011442)one of several TAFs that binds TBP and participates in the formation of the transcription factor IID (TFIID) complex, is the carboxyl (C)-terminal domain of TATA-binding protein (TBP)-associated factor 6 (TAF6). TFIID significantly influences both the recognition of promoter DNA and the assembly of the preinitiation complex.
