Gene Group (FlyBase)
TRANSCRIPTION FACTOR II D -
The general transcription factor complex Transcription factor II D (TFIID) plays an important role in recruiting the transcription machinery to core promoters. TFIID is a complex composed of TBP and several TBP-associated factors. (Adapted from FBrf0125116 and FBrf0156065).
Protein Function (UniProtKB)
The TFIID basal transcription factor complex plays a major role in the initiation of RNA polymerase II (Pol II)-dependent transcription (By similarity). TFIID recognizes and binds promoters with or without a TATA box via its subunit TBP, a TATA-box-binding protein, and promotes assembly of the pre-initiation complex (PIC) (By similarity). Component of the short interfering RNAs (siRNAs)-directed RISC loading complex (siRLC) which acts in the dsRNA-mediated RNA interference (RNAi) pathway by siRNAs into the RNA-induced silencing complex (siRISC), the siRNA then serves as a guide to direct the siRISC to complementary endogenous or viral RNA transcripts for degradation or silencing (PubMed:26257286). Promotes formation of the siRLC by facilitating Dcr-2-R2D2 tetramerization to enhance siRNA binding and siRISC loading activities (PubMed:26257286).

  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)

            Taf11 is part of the RISC loading complex (RLC). It appears to assemble the RLC by facilitating tetramerisation of Dcr-2-r2d2, enhancing RNAi efficiency.

            dsRNA has been made from templates generated with primers directed against this gene.

            The proteins encoded by Tbp, Taf1, Taf2 and Taf11 are likely peripheral subunits of TFIID.

            Identified with: LP03430 <up>FlyBase curator comment: EST subsequently found to be chimeric</up>.

            Does not interact, in vitro, with human thryroid-hormone receptor-β.

            The assembly and purification of various functional Tbp TAF complexes demonstrate that Tbp plus the TAFs is sufficient to replace endogenous TFIID to support activated transcription in vitro.

            Taf12 and Taf11 join the TfIID complex through interaction with one or more of the larger subunits and only Taf12 may be in contact with Tbp.
