Ptn 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 Rattus norvegicus (Rat) 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 Secreted growth factor that mediates its signal through cell-surface proteoglycan and non-proteoglycan receptors. Binds cell-surface proteoglycan receptor via their chondroitin sulfate (CS) groups. Thereby regulates many processes like cell proliferation, cell survival, cell growth, cell differentiation and cell migration in several tissues namely neuron and bone. Also plays a role in synaptic plasticity and learning-related behavior by inhibiting long-term synaptic potentiation. Binds PTPRZ1, leading to neutralization of the negative charges of the CS chains of PTPRZ1, inducing PTPRZ1 clustering, thereby causing the dimerization and inactivation of its phosphatase activity leading to increased tyrosine phosphorylation of each of the PTPRZ1 substrates like ALK or AFAP1L2 in order to activate the PI3K-AKT pathway. Through PTPRZ1 binding, regulates endothelial cell migration and controls oligodendrocyte precursor cell differentiation. Forms a complex with PTPRZ1 and integrin alpha-V\/beta-3 (ITGAV:ITGB3) that stimulates endothelial cell migration through SRC dephosphorylation and activation that consequently leads to ITGB3 'Tyr-773' phosphorylation. In adult hippocampus promotes dendritic arborization, spine development, and functional integration and connectivity of newborn granule neurons through ALK by activating AKT signaling pathway. Binds GPC2 and chondroitin sulfate proteoglycans (CSPGs) at the neuron surface, leading to abrogation of binding between PTPRS and CSPGs and neurite outgrowth promotion. Binds SDC3 and mediates bone formation by recruiting and attaching osteoblasts\/osteoblast precursors to the sites for new bone deposition. Binds ALK and promotes cell survival and cell proliferation through MAPK pathway activation. Inhibits proliferation and enhances differentiation of neural stem cells by inhibiting FGF2-induced fibroblast growth factor receptor signaling pathway. Mediates regulatory mechanisms in normal hemostasis and in hematopoietic regeneration and in maintaining the balance of myeloid and lymphoid regeneration. In addition may play a role in the female reproductive system, auditory response and the progesterone-induced decidualization pathway.\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 \u003cli\u003eE. coli expression can limit eukaryotic post-translational modifications; for modification-dependent biology, interpret results accordingly.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry for P63090 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P63090\/entry - NCBI Gene search (Ptn) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=Ptn - PubMed search (Ptn) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=Ptn - RCSB PDB search (Ptn) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=Ptn - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065315287405,"sku":"CSB-EP019009RA-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065481257325,"sku":"CSB-EP019009RA-100UG","price":729.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065481290093,"sku":"CSB-EP019009RA-20UG","price":388.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP019009RA-SDS.jpg?v=1772476562","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-rat-pleiotrophin-ptn-bhp10510271","provider":"BioHippo","version":"1.0","type":"link"}
