Summary: Initiation of transcription by RNA polymerase II requires the activities of more than 70 polypeptides. The protein that coordinates these activities is transcription factor IID (TFIID), which binds to the core promoter to position the polymerase properly, serves as the scaffold for assembly of the remainder of the transcription complex, and acts as a channel for regulatory signals. TFIID is composed of the TATA-binding protein (TBP) and a group of evolutionarily conserved proteins known as TBP-associated factors or TAFs. TAFs may participate in basal transcription, serve as coactivators, function in promoter recognition or modify general transcription factors (GTFs) to facilitate complex assembly and transcription initiation. This gene encodes an integral subunit of TFIID associated with all transcriptionally competent forms of that complex. This subunit interacts strongly with two TFIID subunits that show similarity to histones H3 and H4, and it may participate in forming a nucleosome-like core in the TFIID complex. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]

Protein	Gene	Interaction	Pubs
Tat	tat	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	PubMed
	tat	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	PubMed
	tat	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	PubMed
	tat	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	PubMed
	tat	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	PubMed

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
