Binds with low affinity to interleukin-13 (IL13). Together with IL4RA can form a functional receptor for IL13. Also serves as an alternate accessory protein to the common cytokine receptor gamma chain for interleukin-4 (IL4) signaling, but cannot replace the function of IL2RG in allowing enhanced interleukin-2 (IL2) binding activity.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eQuantitative mapping of ligand\/receptor signaling to downstream phospho- and transcriptional programs.\u003c\/li\u003e\n\u003cli\u003eActivity assay development for kinetics, substrate scope, and inhibitor\/activator profiling.\u003c\/li\u003e\n\u003cli\u003eUse of recombinant standards to improve assay calibration and cross-study comparability.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterleukin-13 receptor subunit alpha-1(IL13RA1) is a subunit of the interleukin 13 receptor. This subunit forms a receptor complex with IL4 receptor alpha, a subunit shared by IL13 and IL4 receptors. The human IL13-Rα1 was originally cloned based on sequence homology to the mouse IL13-Rα1, it share 76% aa sequence identity. Human The IL13-Rα1 cDNA encodes a 427 amino acid (aa) residue precursor protein with a putative 21 aa residue signal peptide, a 324 aa residue extracellular domain, a 23 aa residue transmembrane region and a 59 aa residue cytoplasmic tail. The extracellular domain of IL13-Rα1 is also closely related to that of IL13-Rα2. It binds with low affinity to interleukin-13(IL13). IL13RA1 serves as a primary IL13- binding subunit of the IL13 receptor, and may also be a component of IL4 receptors. This protein has been shown to bind tyrosine kinase TYK2, and thus may mediate the signaling processes that lead to the activation of JAK1, STAT3 and STAT6 induced by IL13 and IL4.\u003c\/p\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStandard curve or spike-in reference for quantitative assays involving IL13RA1\u003c\/li\u003e\n\u003cli\u003eBinding interaction studies (e.g., SPR\/BLI or plate-based binding formats)\u003c\/li\u003e\n\u003cli\u003eCell-based stimulation studies with downstream marker readouts (conceptual)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRecombinant constructs may not capture all native isoforms or PTMs.\u003c\/li\u003e\n\u003cli\u003eConsider tag- or host-related effects when interpreting binding or activity.\u003c\/li\u003e\n\u003cli\u003eUse appropriate blanks and matrix\/control concepts to separate signal from background.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProtKB P78552 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P78552 - NCBI Gene search: IL13RA1 — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=IL13RA1 - Ensembl search: IL13RA1 — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=IL13RA1 - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ - NCBI Bookshelf — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/books\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53053388161389,"sku":"CSB-AP004571HU-1MG","price":1836.0,"currency_code":"USD","in_stock":true},{"title":"500 ug","offer_id":53053498294637,"sku":"CSB-AP004571HU-500UG","price":1160.0,"currency_code":"USD","in_stock":true},{"title":"50 ug","offer_id":53053498327405,"sku":"CSB-AP004571HU-50UG","price":204.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-AP004571HU.jpg?v=1772177584","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-interleukin-13-receptor-subunit-alpha-1-il13ra1-partial-active-bhp10506609","provider":"BioHippo","version":"1.0","type":"link"}
