Immunofluorescence staining of Hela cell with CSB-PA352689LA01HU at 1:160, counter-stained with DAPI. The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

產品詳情

產品描述：

The rabbit was immunized with recombinant human Syncytin-2 protein (16-250aa) to produce the ERVFRD-1 polyclonal antibody, which is an IgG isoform and exhibits a liquid form. This ERVFRD-1 antibody underwent antigen affinity purification. This ERVFRD-1 antibody shows reactivity with the human ERVFRD-1 protein.

The specificity of this ERVFRD-1 antibody has been validated in ELISA, WB, and IHC. The ERVFRD-1 polyclonal antibody can be used to detect and study the expression of the ERVFRD-1 protein as well as to visualize the distribution of the ERVFRD-1 protein. ERVFRD-1 is a critical protein for placental development and the healthy development of the fetus during pregnancy.

功能：

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.

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

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
