HIV protein: Tat
Interaction type: interacts with
Description: TATA binding protein (TBP)-associated factors (TAFs) in the TFIID complex are required for activation by transcription factors, but are dispensable for HIV-1 Tat LTR transactivation function

HIV protein: Tat
Interaction type: recruits
Description: A novel function of LBP-1, restricting HIV-1 transcription at the level of elongation by preventing the binding of TFIID to the promoter, is suppressed by HIV-1 Tat, indicating Tat helps recruit TFIID to the HIV-1 LTR

HIV protein: Tat
Interaction type: interacts with
Description: Interaction of TFIID with the HIV-1 LTR, and therefore presumably HIV-1 Tat protein, is primarily dependent on the LTR TATA element and may also be stabilized or regulated by flanking E box motifs and basic helix-loop-helix proteins such as AP-4 and E47

HIV protein: Tat
Interaction type: binds
Description: HIV-1 Tat binds, through amino acids 36-50, directly to the TBP subunit of the TFIID holoenzyme complex (which includes at least TFIID subunits p250, p125, p70, TBP, and p30), and increases the interaction of TFIID with the HIV-1 LTR promoter

HIV protein: Tat
Interaction type: stabilizes
Description: HIV-1 Tat stabilizes the interaction of TFIIA with TFIID, and TFIIA and TFIID are required to reconstitute Tat-specific and TAR-dependent activation of HIV transcription in vitro
