Binds to ssRNA containing the consensus sequence 5'-AGGUAA-3'. Binds to nascent pre-mRNAs and acts as a molecular mediator between RNA polymerase II and U1 small nuclear ribonucleoprotein thereby coupling transcription and splicing. Also binds its own pre-mRNA and autoregulates its expression; this autoregulation mechanism is mediated by non-sense-mediated decay. Plays a role in DNA repair mechanisms by promoting D-loop formation and homologous recombination during DNA double-strand break repair. In neuronal cells, plays crucial roles in dendritic spine formation and stability, RNA transport, mRNA stability and synaptic homeostasis\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\u003ePrepare aliquots of FUS for reproducible in vitro assays (minimize freeze–thaw).\u003c\/li\u003e\n\u003cli\u003eUse FUS as a calibration standard in quantitative assays (standard curve setup).\u003c\/li\u003e\n\u003cli\u003eMeasure binding interactions to FUS by SPR\/BLI (kinetic profiling in vitro).\u003c\/li\u003e\n\u003cli\u003eGenerate antibodies to FUS and benchmark specificity in ELISA\/WB (control samples).\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 (P35637) — UniProt: https:\/\/www.uniprot.org\/uniprotkb\/P35637 - NCBI Gene search (FUS) — NCBI: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=FUS - PubMed search — NLM: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=FUS - 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":53059294724461,"sku":"CSB-EP009069HUc7-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53059433038189,"sku":"CSB-EP009069HUc7-100UG","price":729.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53059433070957,"sku":"CSB-EP009069HUc7-20UG","price":388.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP009069HUc7-SDS.jpg?v=1772280321","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-rna-binding-protein-fus-fus-bhp10515729","provider":"BioHippo","version":"1.0","type":"link"}
