Usage
For Research Use Only. Not for use in diagnostic or therapeutic procedures.
May function as an inhibitor of Wnt/beta-catenin signaling by indirectly interacting with LRP6 and blocking Wnt3a-dependent LRP6 internalization.
Gene References into Functions
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
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
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
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
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 signallingPMID:25066861
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
The surface expression of 5T4 marks the use of the CXCR4 rather than the CXCR7 receptor, with distinct consequences for CXCL12 exposure.PMID:22956548
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
Glycosylation and epitope mapping of the 5T4 glycoprotein oncofoetal antigenPMID:11903056
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
there is a repertoire of CD8 T cell recognition of 5T4 in normal human donors and some candidate HLA-A*0201 epitopes have been identifiedPMID:16646078
the mRNA expression of trophoblast glycoprotein is up-regulated in cells circulating within blood from women with preeclampsia.PMID:17978129
5T4-based cancer vaccine: cytotoxic T lymphocyte epitopes identified in Trovax-vaccinated colorectal cancer patientsPMID:18567615
colorectal cancer patients who had preexisting cell proliferative responses to 5T4 were longer-term survivorsPMID:18833005

Cell membrane; Single-pass type I membrane protein.
Tissue Specificity
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.
