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 one of the smaller subunits of TFIID that binds to the basal transcription factor GTF2B as well as to several transcriptional activators such as p53 and VP16. In human, TAF9 and AK6 (GeneID: 102157402) are two distinct genes that share 5' exons. A similar but distinct gene (TAF9L) has been found on the X chromosome and a pseudogene has been identified on chromosome 19. Alternative splicing results in multiple transcript variants.

Protein Gene Interaction Pubs
Tat 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 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 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
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

RefSeqs maintained independently of Annotated Genomes

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.
