TATA box-binding protein-like protein 1 (TBPL1), partial, human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-185aa. Protein Length: Partial. Tag Info: N-terminal 6xHis-SUMO-tagged. Target Protein Sequence: MDADSDVALD ILITNVVCVF RTRCHLNLRK IALEGANVIY KRDVGKVLMK LRKPRITATI WSSGKIICTG ATSEEEAKFG ARRLARSLQK LGFQVIFTDF KVVNVLAVCN MPFEIRLPEF TKNNRPHASY EPELHPAVCY RIKSLRATLQ IFSTGSITVT GPNVKAVATA VEQIYPFVFE SRKEI. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Part of a specialized transcription syst that mediates the transcription of most ribosomal proteins through the 5'-TCT-3' motif which is a core promoter elent at these genes. Ses to also mediate the transcription of NF1. Does not bind the TATA box. Reference: TRF2, but not TBP, mediates the transcription of ribosomal protein genes.Wang Y.L., Duttke S.H., Chen K., Johnston J., Kassavetis G.A., Zeitlinger J., Kadonaga J.T.Genes Dev. 28:1550-1555(2014). Function: Part of a specialized transcription system that mediates the transcription of most ribosomal proteins through the 5'-TCT-3' motif which is a core promoter element at these genes. Seems to also mediate the transcription of NF1. Does not bind the TATA box.
