Form
Liquid or 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.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. 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.
Troubleshooting and FAQs
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

Function
This endogenous retroviral envelope protein has retained its original fusogenic properties and participates in trophoblast fusion and the formation of a syncytium during placenta morphogenesis. The interaction with MFSD2A is apparently important for this process.; Endogenous envelope proteins may have kept, lost or modified their original function during evolution but this one can still make pseudotypes with MLV, HIV-1 or SIV-1 virions and confer infectivity. Retroviral envelope proteins mediate receptor recognition and membrane fusion during early infection. The surface protein mediates receptor recognition, while the transmembrane protein anchors the envelope heterodimer to the viral membrane through one transmembrane domain. The other hydrophobic domain, called fusion peptide, mediates fusion of the viral membrane with the target cell membrane.

  1. genetic predisposition in ERVFRDE-1 may be associated with an increased risk of preeclampsia. This polymorphism is possibly involved in the regulation of syncytin-2 expression in preeclamptic placenta. PMID: 29750965
  2. N-glycans at residues 133, 312, 332 and 443 of syncytin-2 are required for optimal fusion induction, and that single-nucleotide polymorphism C46R, N118S, T367M, R417H, V483I and T522M can alter the fusogenic function of syncytin-2. PMID: 26853155
  3. Decreased syncytin-2 and MFSD2 proteins in gestational diabetic placentas might cause abnormal syncytiotrophoblast formation and possibly be involved in the pathology PMID: 26875564
  4. ERVWE1, ERVFRDE1 and ERV3 transcription was down-regulated in hydatidiform moles and gestational trophoblastic neoplasia. PMID: 26992684
  5. These results thereby demonstrate that induced expression of Syncytin-2 is highly dependent on the interaction of bZIP-containing transcription factors to a CRE/AP-1 motif and that this element is important for the regulation of Syncytin-2 expression PMID: 25781974
  6. MFSD2a, the Syncytin-2 receptor, is important for trophoblast fusion. PMID: 23177091
  7. results further highlighted the existence of a correlation between the extent of the decrease in the expression levels of both syncytins 1 and 2 fusogenic proteins and the degree of severity of preeclampsia symptoms PMID: 21493955
  8. Analysis of non-spliced ERVFRDE1 mRNAs and env mRNAs detected efficient splicing of endogenously expressed RNAs in trophoblastic but not in non-placental cells. PMID: 21771862
  9. The crystal structure of a central fragment of syncytin 2 "fossil" ectodomain is reported, allowing a remarkable superposition with the structures of the corresponding domains of present-day infectious retroviruses PMID: 16140326
  10. immunolocalized only in the villous trophoblast of the chorionic villi, at the level of cytotrophoblastic cells PMID: 16714059
  11. findings show that in both humans and mice, one of the two syncytins (human syncytin-2 and mouse syncytin-B) is immunosuppressive and, rather unexpectedly, the other (human syncytin-1 and mouse syncytin-A) is not PMID: 18077339
  12. Syncytin 2 expression illustrates the abnormal trophoblast differentiation observed in placenta of fetal T21-affected pregnancies. PMID: 18215254
  13. expression decreased in preeclamptic placentas; may function as a second fusogenic protein for placental cell fusion PMID: 18650494
  14. These results highlight the importance of Syncytin-2 in BeWo and primary human trophoblast cell fusion. PMID: 19616006
