CC   -!- FUNCTION: General transcription factor that functions at the core of
CC       the DNA-binding multiprotein factor TFIID. Binding of TFIID to the TATA
CC       box is the initial transcriptional step of the pre-initiation complex
CC       (PIC), playing a role in the activation of eukaryotic genes transcribed
CC       by RNA polymerase II.
CC   -!- SUBUNIT: Belongs to the TFIID complex together with the TBP-associated
CC       factors (TAFs). Binds DNA as monomer.
CC   -!- SUBCELLULAR LOCATION: Nucleus.
CC   -!- SIMILARITY: Belongs to the TBP family. {ECO:0000305}.
