Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Tag?type?will?be?determined?during?the?manufacturing?process.

The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
產品提供形式：

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.
復溶：

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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

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.
貨期：

Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點詳情

功能：

Component of the general transcription and DNA repair factor IIH (TFIIH) core complex, which is involved in general and transcription-coupled nucleotide excision repair (NER) of damaged DNA and, when complexed to CAK, in RNA transcription by RNA polymerase II. In NER, TFIIH acts by opening DNA around the lesion to allow the excision of the damaged oligonucleotide and its replacement by a new DNA fragment. In transcription, TFIIH has an essential role in transcription initiation. When the pre-initiation complex (PIC) has been established, TFIIH is required for promoter opening and promoter escape. Phosphorylation of the C-terminal tail (CTD) of the largest subunit of RNA polymerase II by the kinase module CAK controls the initiation of transcription. The N-terminus of GTF2H2 interacts with and regulates XPD whereas an intact C-terminus is required for a successful escape of RNAP II form the promoter.
基因功能參考文獻：
1. interface variants between the p34 and p44 subunits only mildly affected the association between the full length proteins and did not impinge on TFIIH activities due to the presence of an additional interface involving the C4 domain of p34. PMID: 28977422
2. Advanced oxidation protein products down-regulate the expression of calcium transport channels through p44/42 MAPK signaling mechanisms in the small intestinal epithelium. PMID: 25801217
3. Together, these results suggest that p44/WDR77 expression causes the non-sensitivity of proliferating cells to TGFbeta signaling, thereby contributing to cellular proliferation during lung tumorigenesis. PMID: 24944016
4. No correlation was found for p44 and occludin gene copy number and spinal muscular atrophy PMID: 21821450
5. miR-27a was identified as a key regulator of p44 mRNA. Moreover, miR-27a was shown to destabilize the p44 subunit of the TFIIH complex during the G2-M phase, thereby modulating the transcriptional shutdown observed during this transition. PMID: 21558443
6. p52 Mediates XPB function within the transcription/repair factor PMID: 12080057
7. p44 of TFIIH has a role in binding to the nonstructural protein of Rift Valley fever virus to form nuclear filamentous structures PMID: 14980221
8. solution structure of p44-(321-395) shows topology differs from other reported RING domains by a circular permutation of the extended secondary structure elements; mutagenesis suggests tight binding to p34 is mediated by hydrophobic interactions PMID: 15790571
9. Impaired transcription in IPF is associated with decreased concentrations of transcription factor II-H in alveolar macrophages and may alter the intraalveolar milieu in IPF. PMID: 17332483
