  • Immunofluorescence staining of MCF-7 cells with CSB-PA822274LA01HU at 1:133, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

NECTIN4 antibody is a rabbit polyclonal IgG raised against recombinant NECTIN4 (91-199aa)of human origin. It was synthesized in a rabbit and purified by protein G. Its purity is over 95%. This NECTIN4 antibody is recommended for the detection of human NECTIN4 protein by ELISA and IF.

NECTIN4 is primarily expressed on the surface of epithelial cells, where it plays a critical role in maintaining the integrity of epithelial tissues and facilitating intercellular communication. It od also implicated in cell proliferation, differentiation, and apoptosis. Dysregulation of NECTIN4 expression or function has been related to cancer, viral infections, autoimmune disorders, and other diseases.

Target Background

Seems to be involved in cell adhesion through trans-homophilic and -heterophilic interactions, the latter including specifically interactions with NECTIN1. Does not act as receptor for alpha-herpesvirus entry into cells.; (Microbial infection) Acts as a receptor for measles virus.
Gene References into Functions
  1. We suggest that Nectin-4 is a relevant prognostic factor and a therapeutic target in luminalB (HER2 negative) breast cancer. PMID: 28778498
  2. Nectin-4 promotes cell-cell adhesion/aggregation, migration, and proliferation of ovarian tumor cells. PMID: 28038455
  3. Nectin-4 is not only a BCSC marker but also a breast cancer metastasis marker PMID: 28600142
  4. This study suggests that PVRL4 is post-transcriptionally regulated by miR-128 and miR-31. PMID: 27507538
  5. High Nectin-4 expression is associated with neoplasms. PMID: 27013195
  6. We show that Measles virus gains entry into MCF7, DLD-1, and HTB-20 cancer cells through a PVRL4-mediated macropinocytosis pathway and identified the typical cellular GTPase and kinase involved. PMID: 28250131
  7. nectin-4 serves as a stimulatory co-receptor for the prolactin receptor by regulating the feedback inhibition of SOCS1 in the JAK2-STAT5a signaling pathway PMID: 28258213
  8. Nectin-4 is both a new promising prognostic biomarker and specific therapeutic target for Triple-negative breast cancers PMID: 27998973
  9. ADAM17 and ADAM10 cleave Nectin-4 and release soluble Nectin-4 (sN4). PMID: 28232483
  10. The data presented in this study suggested that nectin-4 may be a therapeutic target for systemic lupus erythematous through affecting the cell apoptosis PMID: 26617807
  11. Nectin-4 is critical for gallbladder cancer cell progression via PI3K/AKT pathway activation of Rac1. PMID: 26949052
  12. Nectin-4 expression, when compared with control group, was higher in endometriotic lesions of patients having ovarian endometriosis and peritoneal endometriosis. This difference was significant in the endometrium of patients having endometriosis. PMID: 27328518
  13. Transformation of breast cancer cells is dependent on PVRL4. PMID: 23682311
  14. Nectin-4 is a significant prognostic predictor, and may play a critical role in pancreatic cancer. Nectin-4 may be novel therapeutic target for pancreatic cancer. PMID: 25888293
  15. In airway epithelial cells, measles virus spread requires the nectin-4/afadin complex and is based on cytoplasm transfer between columnar cells. PMID: 25926640
  16. The present study described clinical investigation of the EDSS1 identified in a large consanguineous family; DNA sequence analysis revealed a novel homozygous nonsense mutation (181C>T, p.Asp61*) in the PVRL4 gene. PMID: 25529316
  17. Ovarian tissue expression and serum nectin 4 appear to be potential markers in ovarian cancer. PMID: 25019423
  18. Authors show that the same key residues in the BC and FG loops of nectin-4 govern binding to the measles virus attachment protein hemagglutinin (H) and cell entry, nectin-4 homodimerization, and heterodimerization with nectin-1. PMID: 25275122
  19. data outline a synergistic action of nectin-1 and -4 in the early steps of AJ formation and implicate this interaction in modulating the Rac1 signaling pathway PMID: 24577405
  20. Ablation of nectin4 binding compromises CD46 usage by a hybrid vesicular stomatitis virus/measles virus. PMID: 24335299
  21. Thus, while nectin-4 and CD46 interact functionally with the measles virus H protein beta4-beta5 hydrophobic groove, SLAM merely covers it. PMID: 23760251
  22. Data suggest that expression of nectin-4 is up-regulated in eutopic endometrium of patients with endometriosis compared with control subjects. PMID: 22926846
  23. We show that human nectin4 is fully functional as a canince distemper virus receptor. PMID: 23174504
  24. structure of the membrane-distal domain of nectin-4 in complex with measles virus hemagglutinin (MV-H; structure shows nectin-4 binds the MV-H beta4-beta5 groove exclusively via its N-terminal IgV domain; the contact interface is dominated by hydrophobic interactions PMID: 23202587
  25. crystals of nectin-4 diffracted to 1.8 A resolution and belonged to space group P2(1), with unit-cell parameters a = 33.1, b = 51.7, c = 56.9 A, beta = 94.7 degrees PMID: 22869128
  26. measles virus targets nectin-4 to emerge in the airways PMID: 22048310
  27. Measles virus infection reduced PVRL4 surface expression in MCF7 cells, a property that is characteristic of receptor-associated viral infections. PMID: 21901103
  28. The findings of study suggest that increased expression of Nectin-4 may indicate a worse prognosis in breast cancer patients. PMID: 21526486
  29. Sequence analysis revealed a homozygous missense mutation (c.635C>G; p.Pro212Arg) in the recently reported PVRL4 gene causing EDSS1 PMID: 21346770
  30. Ectoderma dysplasia-syndactyly syndrome. Second example of "nectinopathy". PMID: 21333831
  31. nectin 4 may serve as a potential biomarker that helps discriminate benign gynecologic diseases from ovarian cancer in a panel with CA125. PMID: 20959669
  32. Ectodermal dysplasia-syndactyly syndrome is the second known "nectinopathy" caused by mutations in a nectin adhesion molecule. PMID: 20691405
  33. the active form of TACE is overexpressed in breast tumors and may indicate that TACE is responsible for Nectin-4 shedding not only in vitro but also in vivo PMID: 15784625
  34. Nectin-4 was not detected in normal breast epithelium; by contrast Nectin-4 was expressed in ductal breast carcinoma. PMID: 17474988
  35. Nectin-4 might play a significant role in lung carcinogenesis, and it should be a new candidate serum and tissue biomarker, as well as a therapeutic target. PMID: 19679554
