Conjugate 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.

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.
Form Lyophilized powder
Buffer before Lyophilization 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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage Condition Store at -20°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.
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.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
(From Uniprot)
Low affinity ligand for the ERBB4 tyrosine kinase receptor. Concomitantly recruits ERBB1 and ERBB2 coreceptors, resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors. Does not bind to the ERBB1, ERBB2 and ERBB3 receptors (By similarity).
Gene References into Functions
  1. Nrg4 is highly and preferentially expressed in healthy adipocytes, while its expression was substantially reduced in obesity. Nrg4 activated endothelial angiogenic functions and angiogenesis both in vitro and in vivo. PMID: 29902456
  2. Serum NRG4 values were significantly elevated in the Gestational Diabetes Mellitus (GDM) group compared to the control group and is associated with metabolic parameters of GDM. PMID: 29282998
  3. circulating Nrg4 concentrations are inversely associated with subclinical atherosclerosis in obese adults; circulating Nrg4 might play a role in identifying patients at high risk for cardiovascular disease PMID: 27819316
  4. The circulating Nrg4 level is elevated in the prediabetic and diabetic patients compared to control and is an independent risk factor associated with diabetes. PMID: 27862843
  5. High serum Nrg4 levels are associated with type 2 diabetes mellitus. PMID: 27329015
  6. NRG4 and its receptor ErbB4 are present in human breast milk and developing human intestine, respectively. Thus, NRG4-ErbB4 signaling may be a novel pathway for therapeutic intervention or prevention in NEC. PMID: 25216938
  7. Nrg4 might have a protective role in the development of Non-alcoholic fatty liver disease (NAFLD). PMID: 26476959
  8. results establish Nrg4 as a brown fat-enriched endocrine factor with therapeutic potential for the treatment of obesity-associated disorders, including type 2 diabetes and nonalcoholic fatty liver disease (NAFLD). PMID: 25401691
  9. Pharmacological inhibition of PI3K/Akt signaling reversed the anti-apoptotic effects of NRG4, confirming the role of this cascade in NRG4-induced cell survival PMID: 23033483
  10. The recombinant neuregulin 4 induced the tyrosine phosphorylation of HER4. PMID: 21805036
  11. NRG4 overexpression is associated with advanced-stage prostate cancer PMID: 17545517
  12. describes a novel splice variant of the NRG4 gene, NRG4A2, which encodes a C-terminal region containing a predicted type I PDZ-binding peptide PMID: 17684490
  13. NRG4 was positive in almost all breast cancers studied. PMID: 17962208
  14. Neuregulin-4 expression is downregulated during urinary bladder cancer progression PMID: 15583696
