Protein Length | Full Length |
Mol. Weight | 37.0kDa |
Research Area | Transcription |
Form | Liquid or Lyophilized powder |
Buffer | Liquid form: default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. Lyophilized powder form: the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. |
Reconstitution | Briefly centrifuged the vial prior to opening to bring the contents to the bottom. Reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL. It is recommended to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. The default final concentration of glycerol is 50%. |
Storage | 1. Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. 2. Avoid repeated freeze-thaw cycles. 3. Store working aliquots at 4°C for up to one week. 4. In general, protein in liquid form is stable for up to 6 months at -20°C/-80°C. Protein in lyophilized powder form is stable for up to 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. |
Target Details
Target Function | 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. |
Subcellular Location | Nucleus. |
Protein Families | TFIIE beta subunit family |
Database References | |
Associated Diseases | Trichothiodystrophy 6, non-photosensitive (TTD6) |
Gene Functions References
- 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
- 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
- PC4 plays essential roles in the transition step from transcription initiation to elongation by binding to melted DNA in collaboration with TFIIEbeta. PMID: 25308091
- 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
- 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
- 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
