DPP4 refers to a protein target that is studied across multiple biological contexts; annotations and nomenclature can vary by species and isoform. This product corresponds to the Homo sapiens (Human) sequence context, which can be important when comparing homologs or orthologs across model systems. For curated functional annotations, domains, and sequence features, consult primary databases (e.g., UniProt\/NCBI) and the recent literature for the specific organism and isoform.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eMapping pathway dependencies and signaling networks that drive tumor growth and drug resistance.\u003c\/li\u003e \u003cli\u003eDeveloping and benchmarking biomarker assays (e.g., immunoassays or binding reagents) for candidate targets.\u003c\/li\u003e \u003cli\u003eCharacterizing protein variants, domains, or interaction partners relevant to targeted therapeutics and precision oncology.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelevance:\u003c\/strong\u003e Cell surface glycoprotein receptor involved in the costimulatory signal essential for T-cell receptor (TCR)-mediated T-cell activation . Acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC . Its binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor\/CD3-dependent manner . Its interaction with ADA also regulates lymphocyte-epithelial cell adhesion . In association with FAP is involved in the pericellular proteolysis of the extracellular matrix (ECM), the migration and invasion of endothelial cells into the ECM . May be involved in the promotion of lymphatic endothelial cells adhesion, migration and tube formation . When overexpressed, enhanced cell proliferation, a process inhibited by GPC3 . Acts also as a serine exopeptidase with a dipeptidyl peptidase activity that regulates various physiological processes by cleaving peptides in the circulation, including many chemokines, mitogenic growth factors, neuropeptides and peptide hormones such as brain natriuretic peptide 32 . Removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini provided that the penultimate residue is proline .; (Microbial infection) Acts as a receptor for human coronavirus MERS-CoV-2.\u003c\/p\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eAssay and standard development for immunoassays or binding-based detection methods.\u003c\/li\u003e \u003cli\u003eProtein–protein interaction studies (e.g., receptor–ligand or complex assembly) using purified components.\u003c\/li\u003e \u003cli\u003eStructure–function analysis, including domain mapping or evaluation of sequence variants.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eIn quantitative assay development, changes in binding or activity readouts are typically interpreted relative to appropriate negative\/positive controls and, where possible, orthogonal assay formats that support the same conclusion.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eRecombinant constructs may represent a defined region (domain) rather than the full-length protein; interpret results in the context of the expressed region.\u003c\/li\u003e \u003cli\u003eTag or fusion elements can aid purification and detection but may influence binding surfaces or oligomerization; consider tag controls when relevant.\u003c\/li\u003e \u003cli\u003eSpecies and isoform differences can affect interaction partners and post-translational modifications; align experimental controls to the intended biological context.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry for P27487 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P27487\/entry - NCBI Gene search (DPP4) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=DPP4 - PubMed search (DPP4) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=DPP4 - RCSB PDB search (DPP4) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=DPP4 - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065320628589,"sku":"CSB-MP007139HU1-1MG","price":2136.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065492136301,"sku":"CSB-MP007139HU1-100UG","price":294.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065492169069,"sku":"CSB-MP007139HU1-20UG","price":118.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-MP0622HU-SDS.jpg?v=1772476680","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-dipeptidyl-peptidase-4-dpp4-bhp10510428","provider":"BioHippo","version":"1.0","type":"link"}
