Has preference for L-aromatic amino acids: converts phenylalanine (Phe), tyrosine (Tyr) and tryptophan (Trp) to phenylpyruvic acid (PP), hydroxyphenylpyruvic acid (HPP), and indole-3-pyruvic acid (I3P), respectively (PubMed:17356132, PubMed:32818467, PubMed:32866000). Also has weak L-arginine oxidase activity (PubMed:26673964). Acts as a negative regulator of anti-tumor immunity by mediating Trp degradation via an indole pyruvate pathway that activates the transcription factor AHR (PubMed:32818467, PubMed:32866000). IL4I1-mediated Trp catabolism generates I3P, giving rise to indole metabolites (indole-3-acetic acid (IAA) and indole-3-aldehyde (I3A)) and kynurenic acid, which act as ligands for AHR, a ligand-activated transcription factor that plays important roles in immunity and cancer (PubMed:32818467, PubMed:32866000). AHR activation by indoles following IL4I1-mediated Trp degradation enhances tumor progression by promoting cancer cell motility and suppressing adaptive immunity (PubMed:32818467). Also has an immunoregulatory function in some immune cells, probably by mediating Trp degradation and promoting downstream AHR activation: inhibits T-cell activation and proliferation, promotes the differentiation of naive CD4(+) T-cells into FOXP3(+) regulatory T-cells (Treg) and regulates the development and function of B-cells (PubMed:17356132, PubMed:25446972, PubMed:25778793, PubMed:28891065). Also regulates M2 macrophage polarization by inhibiting T-cell activation (By similarity). Also has antibacterial properties by inhibiting growth of Gram negative and Gram positive bacteria through the production of NH4(+) and H2O2 (PubMed:23355881). {ECO:0000250|UniProtKB:O09046, ECO:0000269|PubMed:17356132, ECO:0000269|PubMed:23355881, ECO:0000269|PubMed:25446972, ECO:0000269|PubMed:25778793, ECO:0000269|PubMed:26673964, ECO:0000269|PubMed:28891065, ECO:0000269|PubMed:32818467, ECO:0000269|PubMed:32866000}.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch_area\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eApplications\u003c\/b\u003e:ELISA\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTarget_protein\u003c\/b\u003e:IL4I1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReactivity\u003c\/b\u003e:Human\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay type\u003c\/b\u003e:Sandwich\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSensitivity\u003c\/b\u003e:0.09ng\/ml\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDetection range\u003c\/b\u003e:0.19-12ng\/ml\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSample type\u003c\/b\u003e:Serum, plasma or other biological fluids\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFull product name\u003c\/b\u003e:Interleukin 4 Induced Protein 1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSpecies\u003c\/b\u003e:Human\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStorage\u003c\/b\u003e:2-8ºC\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAssay time\u003c\/b\u003e:1h 30m\u003c\/p\u003e\u003cp\u003e\u003cb\u003eUniProt accession\u003c\/b\u003e:Q96RQ9\u003c\/p\u003e\u003cp\u003e\u003cb\u003eMASS(Da)\u003c\/b\u003e:62881\u003c\/p\u003e\u003cp\u003e\u003cb\u003eGeneID\u003c\/b\u003e:259307\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSynonyms\u003c\/b\u003e:IL4I1 FIG1 UNQ636\/PRO1265\u003c\/p\u003e\u003cp\u003e\u003cb\u003eGene names\u003c\/b\u003e:IL4I1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStandard solution\u003c\/b\u003e:24ng\/ml\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48648064467044,"sku":"E2766Hu","price":128800.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_0177fa21-0c6a-4f2a-8ca0-d26161606b21.jpg?v=1782707430","url":"https:\/\/www.genebiosystems.com\/en-jp\/products\/human-interleukin-4-induced-protein-1-il4i1-elisa-kit","provider":"GeneBio ","version":"1.0","type":"link"}
