靶标

  • 功能

    General transcription factor that functions at the core of the DNA-binding multiprotein factor TFIID. 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. Component of the transcription factor SL1/TIF-IB complex, which is involved in the assembly of the PIC (preinitiation complex) during RNA polymerase I-dependent transcription. 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.

  • 组织特异性

    Widely expressed, with levels highest in the testis and ovary.

  • 疾病相关

    Defects in TBP are the cause of spinocerebellar ataxia type 17 (SCA17) [MIM:607136]. Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA17 is an autosomal dominant cerebellar ataxia (ADCA) characterized by widespread cerebral and cerebellar atrophy, dementia and extrapyramidal signs. The molecular defect in SCA17 is the expansion of a CAG repeat in the coding region of TBP. Longer expansions result in earlier onset and more severe clinical manifestations of the disease.

    Chromatin was prepared from U2OS cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 min. The ChIP was performed with 25 µg of chromatin, 8 µg of  ab818 (blue), and 20 µl of Protein A/G sepharose beads. No antibody was added to the beads control (yellow). The last wash was performed with final wash buffer containing 250 mM NaCl. The immunoprecipitated DNA was quantified by real time PCR (Taqman and sybr green approach). Primers and probes are located in the core promoter region of the genes.

The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab818, 1µg/1x106 cells) for 30 min at 22°C. The secondary antibody used was Goat Anti-Mouse IgG H&L (DyLight® 488) preadsorbed (ab96879) secondary antibody at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was Mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

Question

I noticed for your antibody, Anti-TATA binding protein TBP antibody [1TBP18] - Nuclear Loading Control and ChIP Grade (ab818), one of the tested applications is EMSA. I can't find any protocol on your website for how to use this antibody in EMSA. Can you please give me a protocol for this? Thanks in advance for your help!

Answer

You can see this antibody used in a gel shift assay in Thompson NE et al. 2004 Protein Expression and Purification 36: 186-197. However, this publication (which must be purchased to view the entire article) refers to using a protocol for the gel shift assay found in Wiley SR et al. 1991 Proc Natl Acad Sci USA 89: 5814-5818 (available free of charge) with the following modifications:

A 25bp oligonucleotide containing a consensus TATA element was purchased from Promega. The reaction volumes were 20ul and contained 8ng of 5’-end-labeled 32P-labeled oligonucleotide and 10ng of human TATA Binding Protein. The reactions were incubated at 23oC for 15 minutes. For the MAb supershift assays, 40ng of MAb was added, and the reactions were allowed to incubate at 23oC for an additional 15 minutes. The reactions were subjected to electrophoresis in a nondenaturing gradient (4-15%) polyacrylamide gel on a PhastSystem for a total of 140-300Vh. The gel and buffer strips were first soaked in a solution of 1/2x TBE and 2mM MgCl2; the MgCl2 helped to stabilize the TBP/DNA complex in the absence of TFIIB.

Question

Hi,

I repeated the experiment and used RIPA buffer for the nuclear fraction but still I have no signal with the anti-TBP ab818!

Do you have an other nuclear loading controle AB which I could try? Or any suggestions?

Answer

Thank you for your updates. I am very sorry to hear that even after following the suggestions, the antibody still does not perform as it is expected.
I would like to reassure you that our Abpromise applies to your complaint since you purchased this product within the guarantee period. This means that in the event that a product is not functioning in the applications/species cited on the product data sheet (and the problem has been reported within 6 months of purchase) we will happily offer a credit note/refund to the value of the product purchased.
We have alternative antibodies against the same target TBP (ab51841) or against Laminin B1 (ab16048). Please could you take a look at the datasheets of these products and let me how you wish to proceed with your enquiry.
I look forward to hearing from you soon.

Question

Hi,

I have nuclear extraction and wanted to use TBP as a loading control. However, cells were treated with cisplatin at low dose. Would it affect TBP as a loading control? If so, what do you recommend (Nucleolin would be okay?)

Thank you.

Read More
Answer

Thank you for contacting us.

We are happy to help customers find the most suitable products for their research purposes . In our review of this problem it does seem that cisplatin may affect the levels of TBP in cells while nucleolin seems affected mainly in it's distribution; however we are not specialized in this particular field and do not want to recommend a product that may be unsuitable. We encourage customers to consult the latest literature available through PubMed and other resources in order to find the most up-to-date information about their specific research interests.


I am sorry that I could not be more helpful, but I hope that the available literature in this area can provide some clarification. Please do not hesitate to contact us again with other needs or with any questions about our products.
