Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
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.
and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
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.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Recruits TFIIH to the initiation complex and stimulates the RNA polymerase II C-terminal domain kinase and DNA-dependent ATPase activities of TFIIH. Both TFIIH and TFIIE are required for promoter clearance by RNA polymerase.
Gene References into Functions
  1. functional analysis of Trichothiodystrophy causative TFIIEbeta mutation demonstrates that mutant TFIIEbeta strongly reduces the total amount of the entire TFIIE complex, with a remarkable temperature-sensitive transcription defect. PMID: 28973399
  2. We underline role of TFIIE in transcription and its distinction from nucleotide excision repair. Trichothiodystrophy individuals with mutations in GTF2E2 highlight the importance of the direct interaction between TFIIH and TFIIE in transcription process. PMID: 26996949
  3. PC4 plays essential roles in the transition step from transcription initiation to elongation by binding to melted DNA in collaboration with TFIIEbeta. PMID: 25308091
  4. introduced point mutations into two regions located near the carboxy terminus of TFIIE beta and identified the functionally essential amino acid residues that bind to RNA polymerase II PMID: 12665589
  5. TFIIE is an alpha/beta heterodimer in solution; A model for the quaternary architecture of the complex is proposed that provides a structural framework to discuss the function of TFIIE in the context of RNA polymerase II transcription initiation. PMID: 16547462
  6. These data suggest a model in which TFIIE binds to a position adjacent to the initiation site via the forkhead domain, enabling TFIIH to begin opening the promoter. PMID: 19210545
