NCIt definition : Transcription initiation factor TFIID subunit 5 (800 aa, 87 kDa) is encoded by the
human TAF5 gene. This protein plays a role in the assembly of the basal transcription
apparatus.;
NCIt note : TBP-Associated Factor 5 interacts strongly with (histone H4-related) TAFII80 and (histone
H3-related) TAFII31, as well as with TBP, TAFII250, TAFII28, and TAFII20. A component
of the TFTC-HAT complex, TAFII100 contains 1 LisH domain and 6 WD repeats; distinct
TAFII100 domains are required for interaction with TFIIFB and for incorporation into
TFIID.;
