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：

Gap-filling polymerase involved in repair of DNA double-strand breaks by non-homologous end joining (NHEJ). Participates in immunoglobulin (Ig) light chain gene rearrangement in V(D)J recombination.
基因功能參考文獻：
1. Polmu point mutations affecting 2 conserved adjacent residues located in the 8 kDa domain, G174S and R175H, limit the efficiency of accurate NHEJ by Polmu in vitro and in vivo due to decreased template dependency during NHEJ, which renders the error-rate of the mutants higher due to the ability of Polmu to randomly incorporate nucleotides at DSBs. PMID: 28973441
2. Structural accommodation of ribonucleotide incorporation by the DNA repair enzyme polymerase Mu has been described. PMID: 28911097
3. analysis of template-dependent synthesis by human polymerase mu PMID: 26240373
4. A study of how Polmu fixes and/or orients the mobile Loop1 part of the protein in accordance with the substrate on which it is polymerizing. PMID: 24878922
5. specific loop 1 residues contribute to Pol mu's unique ability to catalyze template-dependent NHEJ of DSBs with unpaired 3' ends PMID: 24487959
6. evidence suggests that Polmu could be regulated in vivo by phosphorylation of the BRCT domain (Ser12/Thr21) and of Ser372, affecting the function of loop1; Polmu's most distinctive activities would be turned off at specific cell-cycle phases (S and G2), when these functions might be harmful to the cell PMID: 23933132
7. A specific N-terminal extension of the 8 kDa domain of DNA polymerase mu is potentially implicated in the maintenance of a closed conformation throughout the catalytic cycle, and this study indicated that it could be a target of Cdk phosphorylation. PMID: 23935073
8. A physiological concentration of Mn(2+) ions did benefit Polmicro-mediated non-homologous end joining by improving the efficiency and accuracy of nucleotide insertion. PMID: 23275568
9. The study points at human Polmicro residues His(329) and Arg(387) as responsible for regulating nucleotide expansions occurring during DNA repair transactions, either promoting or blocking, respectively, iterative polymerization. PMID: 23143108
10. The results uncovered a new DNA-binding function for the BRCT domain of Polmicro and demonstrated the importance of several residues located at the primer-binding region, for both DNA-binding and polymerization activities. PMID: 23034807
11. Pol mu binds to DNA through its amino-terminal and pol beta-like regions. PMID: 22897684
12. DNA polymerase mu performs DNA synthesis at a AAF lesion PMID: 11972346
13. Association of DNA polymerase mu (pol mu) with Ku and ligase IV: role for pol mu in end-joining double-strand break repair. PMID: 12077346
14. DNA polymerase mu acts in response to several types of DNA damage with a lesion bypass mechanism PMID: 12228225
15. expression in B-cell non-Hodgkin's lymphomas PMID: 12368208
16. Pol mu's substrate specificity is similar to that of pol beta in most respects but has an approximately 1,000-fold-reduced ability to discriminate against ribonucleotides compared to pol beta PMID: 12640116
17. human DNA polymerase mu has a template-dependent, sequence-independent nucleotidyl transferase activity PMID: 14581466
18. Poliota incorporates a C opposite the gamma-HOPdG adduct with nearly the same efficiency as opposite a nonadducted G residue. The subsequent extension step is performed by Polkappa, which efficiently extends from the C incorporated opposite the adduct. PMID: 15199127
19. DNA polymerase mu has been overexpressed, purified, and its fidelity estimated for incorporation of both deoxynucleotides and ribonucleotides based on pre-steady-state kinetic data under single-turnover conditions. PMID: 15504045
20. Overexpression of DNA polymerase mu in a Burkitt's lymphoma cell line induced an increase in somatic mutations specifically targeted to G/C residues in immunoglobulin variable genes. PMID: 15520469
21. Pol mu promotes accuracy during Ig kappa recombination. PMID: 16061182
22. When the terminal deoxynucleotidyl transferase (TdT) loop1 was deleted, human Polmu lacked TdT activity but improved DNA-binding and DNA template-dependent polymerization. PMID: 16963491
23. Studies shed light on the mechanism by which a rate-limited terminal transferase activity in Polmu could regulate the balance between accuracy and necessary efficiency, providing some variability during NHEJ. PMID: 19805281
