    • IHC image of CSB-RA902876A0HU diluted at 1:100 and staining in paraffin-embedded human placenta tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.

  • 功能：
    May function as an inhibitor of Wnt/beta-catenin signaling by indirectly interacting with LRP6 and blocking Wnt3a-dependent LRP6 internalization.
  • 基因功能参考文献：
    1. In extravillous trophoblasts, 5T4 may function in epithelial-to-mesenchymal transition during placentation. The role of syncytiotrophoblast 5T4 is unknown, but its abundance in shed syncytial vesicles may signify route of sensitization of the maternal immune system. PMID: 28481180
    2. Collectively, these findings demonstrate that an anti-5T4 antibody-drug conjugate reduces the fraction of cancer stem cells (CSC), and prevents local recurrence and suggest a novel therapeutic approach for patients with head and neck squamous cell carcinoma. PMID: 27780858
    3. We obtained GWS evidence (P < 2.7 x 10(-6)) for gene-based association in the total sample with a novel locus, TPBG (P = 1.8 x 10(-6)). PMID: 28183528
    4. In conclusion, the present study provided evidence that TPBG is involved in PDAC metastasis, and that TPBG and its associated signaling pathways may be a suitable target for pancreatic ductal adenocarcinoma therapy. PMID: 25738465
    5. 5T4 expression is mechanistically associated with the directional movement of cells through epithelial mesenchymal transition, facilitation of CXCL12/CXCR4 chemotaxis, blocking of canonical Wnt/beta-catenin while favouring non-canonical pathway signalling PMID: 25066861
    6. Tyrosine 325 plus the leucine-rich repeat 1 surface centered on a second exposed aromatic residue, phenylalanine 97, are essential for inhibition of Wnt/beta-catenin signaling. PMID: 24582434
    7. The surface expression of 5T4 marks the use of the CXCR4 rather than the CXCR7 receptor, with distinct consequences for CXCL12 exposure. PMID: 22956548
    8. 5T4 is a potential new antigen for targeted therapies such as immunotherapy in MPM, as it is overexpressed on mesothelioma cells and recognised by 5T4-specific cytotoxic T-cells. PMID: 22498111
    9. Glycosylation and epitope mapping of the 5T4 glycoprotein oncofoetal antigen PMID: 11903056
    10. Results sugest that 5T4 is a transient marker of human embryonic stem cell differentiation & that 5T4 phenotype, colony seeding density and culture conditions influence the maintenance of pluripotent hES cells and their differentiation to neural lineages. PMID: 16616918
    11. there is a repertoire of CD8 T cell recognition of 5T4 in normal human donors and some candidate HLA-A*0201 epitopes have been identified PMID: 16646078
    12. the mRNA expression of trophoblast glycoprotein is up-regulated in cells circulating within blood from women with preeclampsia. PMID: 17978129
    13. 5T4-based cancer vaccine: cytotoxic T lymphocyte epitopes identified in Trovax-vaccinated colorectal cancer patients PMID: 18567615
    14. colorectal cancer patients who had preexisting cell proliferative responses to 5T4 were longer-term survivors PMID: 18833005

  • 亚细胞定位：
    Cell membrane; Single-pass type I membrane protein.
  • 组织特异性：
    Expressed by all types of trophoblasts as early as 9 weeks of development. Specific for trophoblastic cells except for amniotic epithelium. In adult tissues, the expression is limited to a few epithelial cell types but is found on a variety of carcinoma.
