Description: The TATA binding protein (TBP) is a transcription factor that binds specifically to a DNA sequence TATA box. This DNA sequence is found about 25-30 base pairs upstream of the transcription start site in some eukaryotic gene promoters. TBP, along with a variety of TBP-associated factors, make up the TFIID, a general transcription factor that in turn makes up part of the RNA polymerase II preinitiation complex. As one of the few proteins in the preinitation complex that binds DNA in a sequence-specific manner, it helps position RNA polymerase II over the transcription start site of the gene. However, it is estimated that only 10-20% of human promoters have TATA boxes. Therefore, TBP is probably not the only protein involved in positioning RNA polymerase II. This protein is not suitable for samples where the nuclear envelope has been removed.
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.
Subunit Structure: Binds DNA as monomer (PubMed:2374612, PubMed:2194289). Belongs to the TFIID complex together with the TBP-associated factors (TAFs) (PubMed:9836642, PubMed:27007846). Part of a TFIID-containing RNA polymerase II pre-initiation complex that is composed of TBP and at least GTF2A1, GTF2A2, GTF2E1, GTF2E2, GTF2F1, GTF2H2, GTF2H3, GTF2H4, GTF2H5, GTF2B, TCEA1, ERCC2, ERCC3, TAF1, TAF2, TAF3, TAF4, TAF5, TAF6, TAF7, TAF8, TAF9, TAF10, TAF11, TAF12 and TAF13 (PubMed:27007846). Component of the transcription factor SL1/TIF-IB complex, composed of TBP and at least TAF1A, TAF1B, TAF1C and TAF1D (PubMed:7801123). Association of TBP to form either TFIID or SL1/TIF-IB appears to be mutually exclusive (PubMed:7801123). Interacts with TAF1A, TAF1B and TAF1C (PubMed:7801123). Interacts with TFIIB, NCOA6, DRAP1, DR1 and ELF3 (PubMed:10567404, PubMed:10391676, PubMed:11461703). Interacts with SPIB, SNAPC1, SNAPC2 and SNAPC4 (PubMed:10196196, PubMed:12621023). Interacts with UTF1 (PubMed:9748258). Interacts with BRF2; this interaction promotes recruitment of BRF2 to TATA box-containing promoters (PubMed:11564744, PubMed:26638071). Interacts with UBTF (PubMed:7982918). Interacts with GPBP1 (By similarity). Interacts with CITED2 (By similarity). Interacts with ATF7IP (Probable). Interacts with HIV-1 Tat (PubMed:8121496, PubMed:7608968, PubMed:15719058). Interacts with herpes simplex virus 1 ICP4 (PubMed:8392607). Interacts with human adenovirus E1A protein; this interaction probably disrupts the TBP-TATA complex (PubMed:8146144). Interacts with LLPH (By similarity). Interacts with HSF1 (via transactivation domain) (PubMed:11005381).
Similarity: Belongs to the TBP family.
