Function

General transcription factor that functions at the core of the DNA-binding multiprotein factor TFIID (PubMed:2374612, PubMed:2363050, PubMed:2194289, PubMed:9836642, PubMed:27193682). Binding of TFIID to the TATA box is the initial transcriptional step of the pre-initiation complex (PIC), playing a role in the activation of eukaryotic genes transcribed by RNA polymerase II (PubMed:2374612, PubMed:2363050, PubMed:2194289, PubMed:9836642, PubMed:27193682). Component of a BRF2-containing transcription factor complex that regulates transcription mediated by RNA polymerase III (PubMed:26638071). Component of the transcription factor SL1/TIF-IB complex, which is involved in the assembly of the PIC (pre-initiation complex) during RNA polymerase I-dependent transcription (PubMed:15970593). The rate of PIC formation probably is primarily dependent on the rate of association of SL1 with the rDNA promoter. SL1 is involved in stabilization of nucleolar transcription factor 1/UBTF on rDNA. {PubMed:15970593, PubMed:2194289, PubMed:2363050, PubMed:2374612, PubMed:26638071, PubMed:27193682, PubMed:9836642, ECO:0000305}.

Additionnal Information

This antibody may be used in Western blot and electrophoretic mobility (gel shift) assays to detect mammalian TBP. It may also be used to immunoprecipitate a truncated TBP molecule containing only the N-terminal domain.

Storage Conditions

This antibody is stable for at least one (1) year at -20°C to -70°C. Store product in appropriate aliquots to avoid multiple freeze- thaw cycles.

Specificity

This antibody recognizes an epitope within amino acid residues 1-20 of human, mouse and rat TBP. It does not react with TBP from Drosophila, yeast, silk worm, or Xenopus. Other species not investigated.

Formulation

PBS, pH 7.4.

Target Background

The TATA-binding protein (TBP) plays a central role in the assembly of most eukaryotic transcription initiation complexes. TBP assembles with other proteins to form unique multimeric complexes for each of the three different nuclear RNA polymerases. TBP has been cloned from a variety of species and consists of two distinct domains. The C-terminal domain (~180 amino acids) is highly conserved among species, whereas the N-terminal domain varies considerably in length and sequence among different species. The conserved C-terminal domain contains the DNA-binding region as well as regions that interact with positive and negative regulatory proteins. In human TBP, the non-conserved N-terminal domain includes a stretch of glutamine residues ranging from 26 to 42. Several research groups have found an association between expansion of this polyglutamine tract with rare forms of spinocerebellar ataxia and other neurodegenerative diseases including Huntington's disease.
