Required for normal accumulation of secretory vesicles in hippocampus, pituitary and pancreatic islets. Required for the accumulation of normal levels of insulin-containing vesicles and preventing their degradation. Plays a role in insulin secretion in response to glucose stimuli. Required for normal accumulation of the neurotransmitters norepinephrine, dopamine and serotonin in the brain. In females, but not in males, required for normal accumulation and secretion of pituitary hormones, such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Seems to lack intrinsic enzyme activity. Required to maintain normal levels of renin expression and renin release. May regulate catalytic active protein-tyrosine phosphatases such as PTPRA through dimerization. ; [ICA512-transmembrane fragment]: ICA512-TMF regulates dynamics and exocytosis of insulin secretory granules (SGs); binding of ICA512-TMF to SNTB2\/beta-2-syntrophin is proposed to restrain SGs mobility and exocytosis by tethering them to the actin cytoskeleton depending on UTRN; the function is inhibited by cytoplasmic ICA512-CFF dimerizing with ICA512-TMF and displacing SNTB2. ; [ICA512-cleaved cytosolic fragment]: ICA512-CCF translocated to the nucleus promotes expression of insulin and other granule-related genes; the function implicates binding to and regulating activity of STAT5B probably by preventing its dephosphorylation and potentially by inducing its sumoylation by recruiting PIAS4. Enhances pancreatic beta-cell proliferation by converging with signaling by STAT5B and STAT3. ICA512-CCF located in the cytoplasm regulates dynamics and exocytosis of insulin secretory granules (SGs) by dimerizing with ICA512-TMF and displacing SNTB2 thus enhancing SGs mobility and exocytosis.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDomain- and isoform-aware assay design to improve biological interpretation across model systems.\u003c\/li\u003e\n\u003cli\u003eQuantitative workflows emphasizing calibration standards, spike-in controls, and cross-lot comparability.\u003c\/li\u003e\n\u003cli\u003eIn vitro binding\/kinetics profiling (SPR\/BLI) to connect biochemical interactions with cellular phenotypes.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMeasure Ptprn enzymatic activity with defined substrates\/cofactors (in vitro assay).\u003c\/li\u003e\n\u003cli\u003eEvaluate inhibitor\/activator effects on Ptprn activity across a concentration series.\u003c\/li\u003e\n\u003cli\u003eQuantify Ptprn using calibration standards in plate-based assays (assay development).\u003c\/li\u003e\n\u003cli\u003eProfile binding interactions of Ptprn by SPR\/BLI (kinetic characterization).\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret results in the context of the biological system, assay format, and any known domain\/isoform constraints for the target.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConsider species- and isoform-specific differences when comparing results across models or homologs.\u003c\/li\u003e\n\u003cli\u003eFor quantitative assays, include appropriate negative controls and matrix-matched spike-in concepts to assess non-specific signal.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProtKB entry (Q60673) — UniProt: https:\/\/www.uniprot.org\/uniprotkb\/Q60673 - NCBI Gene search (Ptprn) — NCBI: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=Ptprn - PubMed search — NLM: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=Ptprn - Reactome pathway browser — Reactome: https:\/\/reactome.org\/ - InterPro protein family resource — EMBL-EBI: https:\/\/www.ebi.ac.uk\/interpro\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53059242426733,"sku":"CSB-EP730645MO-1MG","price":1812.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53059328541037,"sku":"CSB-EP730645MO-100UG","price":419.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53059328573805,"sku":"CSB-EP730645MO-20UG","price":224.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP730645MO-SDS.jpg?v=1772280004","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-mouse-receptor-type-tyrosine-protein-phosphatase-like-n-ptprn-partial-bhp10514034","provider":"BioHippo","version":"1.0","type":"link"}
