Human TATA Box Binding Protein (TBP)-Associated Factor, RNA Polymerase I, B, 63kDa (TAF1B) interaction partners

  1. AEP coactivator complex facilitates the initiation of RNAP2-dependent transcription via SL1 activity by loading TBP onto the TATA element.

  2. hCdc14B promotes reactivation of rDNA transcription by dephosphorylating TAFI110. SIRT1 becomes transiently enriched in nucleoli at the onset of mitosis. SIRT1 deacetylates TAFI68 destabilizing SL1 binding to the rDNA promoter

  3. findings show that Rrn7, a subunit of the yeast Pol I core factor, and its human ortholog TAF1B are TFIIB-like factors

  4. TAF1B, a subunit of SL1, is structurally related to TFIIB/TFIIB-like proteins; SL1, essential for Pol I recruitment to rRNA gene promoter, also has an essential postpolymerase recruitment role, operating through TAF1B

  5. Identification of MARCKS, FLJ11383 and TAF1B as putative novel target genes in colorectal carcinomas with microsatellite instability.

  6. The four most frequently mutated genes in colorectal cancers with microsatellite instability were ACVR2 (92%), TAF1B (84%), ASTE1/HT001 (80%) and TGFBR2 (77%).

TATA Box Binding Protein (TBP)-Associated Factor, RNA Polymerase I, B, 63kDa (TAF1B) Protein Profile

Protein Summary

Initiation of transcription by RNA polymerase I requires the formation of a complex composed of the TATA-binding protein (TBP) and three TBP-associated factors (TAFs) specific for RNA polymerase I. This complex, known as SL1, binds to the core promoter of ribosomal RNA genes to position the polymerase properly and acts as a channel for regulatory signals. This gene encodes one of the SL1-specific TAFs.
