Constitutes the main enzyme that mediates monomethylation and asymmetric dimethylation of histone H4 'Arg-3' (H4R3me1 and H4R3me2a, respectively), a specific tag for epigenetic transcriptional activation. May be involved in the regulation of TAF15 transcriptional activity, act as an activator of estrogen receptor (ER)-mediated transactivation, play a key role in neurite outgrowth and act as a negative regulator of megakaryocytic differentiation, by modulating p38 MAPK pathway. Methylates RBM15, promoting ubiquitination and degradation of RBM15. Methylates MRE11 and TP53BP1, promoting the DNA damage response. Methylates FOXO1 and retains it in the nucleus increasing its transcriptional activity. Methylates CHTOP and this methylation is critical for its 5-hydroxymethylcytosine (5hmC)-binding activity. Methylates MAP3K5\/ASK1 at 'Arg-78' and 'Arg-80' which promotes association of MAP3K5 with thioredoxin and negatively regulates MAP3K5 association with TRAF2, inhibiting MAP3K5 stimulation and MAP3K5-induced activation of JNK. Methylates H4R3 in genes involved in glioblastomagenesis in a CHTOP- and\/or TET1-dependent manner. Plays a role in regulating alternative splicing in the heart. Methylates NPRL2 at 'Arg-78' leading to inhibition of its GTPase activator activity and then the GATOR1 complex and consequently inducing timely mTORC1 activation under methionine-sufficient conditions\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 PRMT1 enzymatic activity with defined substrates\/cofactors (in vitro assay).\u003c\/li\u003e\n\u003cli\u003eEvaluate inhibitor\/activator effects on PRMT1 activity across a concentration series.\u003c\/li\u003e\n\u003cli\u003eQuantify PRMT1 using calibration standards in plate-based assays (assay development).\u003c\/li\u003e\n\u003cli\u003eProfile binding interactions of PRMT1 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 (Q99873) — UniProt: https:\/\/www.uniprot.org\/uniprotkb\/Q99873 - NCBI Gene search (PRMT1) — NCBI: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=PRMT1 - PubMed search — NLM: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=PRMT1 - 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":53059318710637,"sku":"CSB-EP859113HU1c7-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53059480289645,"sku":"CSB-EP859113HU1c7-100UG","price":578.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53059480322413,"sku":"CSB-EP859113HU1c7-20UG","price":306.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP859113HU1c7-SDS.jpg?v=1772280423","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-protein-arginine-n-methyltransferase-1-prmt1-partial-bhp10516443","provider":"BioHippo","version":"1.0","type":"link"}
