MeSH definition : A general transcription factor that plays a major role in the activation of eukaryotic
genes transcribed by RNA POLYMERASES. It binds specifically to the TATA BOX promoter
element, which lies close to the position of transcription initiation in RNA transcribed
by RNA POLYMERASE II. Although considered a principal component of TRANSCRIPTION FACTOR
TFIID it also takes part in general transcription factor complexes involved in RNA
POLYMERASE I and RNA POLYMERASE III transcription.;
