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.
Buffer 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.
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 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 3-7 business days
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

This protein is involved in the repair of mismatches in DNA. It is required for dam-dependent methyl-directed DNA mismatch repair. May act as a 'molecular matchmaker', a protein that promotes the formation of a stable complex between two or more DNA-binding proteins in an ATP-dependent manner without itself being part of the final effector complex. The ATPase activity of MutL is stimulated by DNA.
Gene References into Functions
  1. In this review, we describe biochemical, biophysical and structural analyses that have clarified how MutL aids at discriminating the newly synthesized strand from its template and marking it for removal. [review] PMID: 25701376
  2. study found the deletion or insertion of a single LA repeat did not compromise the structural integrity of the protein, nor did it affect MutS- or DNA-binding activity;it severely compromised ATP binding and engagement of the N-terminal domains; both essential activities for proper DNA mismatch repair PMID: 23916559
  3. MutL accumulates from the mismatch site toward strand discrimination site along the DNA. PMID: 22241777
  4. Evidence for ATP-dependent structural rearrangement of nuclease catalytic site in DNA mismatch repair endonuclease MutL PMID: 21953455
  5. C-terminal domain of MutL encompasses a bona fide DNA polymerase III beta-binding motif that mediates a weak, yet specific, interaction between the two proteins. PMID: 21050827
  6. The presence of phosphate minimizes further MutL oligomerization beyond a dimer PMID: 21793594
  7. Studies indicate that a stable MutL-ssDNA interaction is unlikely to occur at physiological salt. PMID: 21103398
  8. MutL homologues play a key role in determining biologic outcome by recruiting and/or activating effector proteins in response to lesion recognition by MutS. PMID: 19953589
  9. Data report the crystal structure of the Escherichia coli MutL C-terminal dimerization domain and the likelihood of its conservation among MutL homologs. PMID: 15470502
  10. revised model for the biological dimer, which has important implications for understanding the heterodimerization of eukaryotic MutL homologues, modeling the MutL holoenzyme and predicting protein-protein interaction sites PMID: 16024043
  11. MutL determines effective DNA homology in recombination processes PMID: 17502621
  12. An increase in mutL gene copies was also able to partially compensate the hypermutator phenotype of a mutS-defective E. coli derivative. PMID: 17825069
  13. Results suggest a mobile MutS-MutL complex in DNA mismatch repair signalling, that leaves the DNA mismatch prior to, or at the time of, activation of downstream effector molecules such as Vsr or MutH. PMID: 19474347
