產(chǎn)品詳情

  • 產(chǎn)品描述：

    The recombinant human L-amino-acid oxidase protein (139-339aa) was injected into a rabbit to trigger an immune response leading to the generation of antibodies against IL4I1. The IL4I1 polyclonal antibody was isolated and purified from the rabbit's serum through protein G affinity chromatography. Its purity exceeds 95%. This rabbit anti-human IL4I1 polyclonal antibody was tested in the ELISA, WB, and IHC. The non-conjugated IgG was purified by protein G affinity chromatography and reached up to 95% in purity. It shows reactivity with the human and mouse IL4I1 proteins and may be used to detect the endogenous levels of IL4I1 protein.

    The target protein IL4I1 is primarily responsible for the degradation of L-tryptophan, which has important implications for the immune response, tissue repair and regeneration, and tumor growth and metastasis.

產(chǎn)品評價

靶點詳情

  • 功能：
    Secreted L-amino-acid oxidase that acts as a key immunoregulator. 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. Also has weak L-arginine oxidase activity. Acts as a negative regulator of anti-tumor immunity by mediating Trp degradation via an indole pyruvate pathway that activates the transcription factor AHR. 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. AHR activation by indoles following IL4I1-mediated Trp degradation enhances tumor progression by promoting cancer cell motility and suppressing adaptive immunity. 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. Also regulates M2 macrophage polarization by inhibiting T-cell activation. Also has antibacterial properties by inhibiting growth of Gram negative and Gram positive bacteria through the production of NH4(+) and H2O2.
  • 基因功能參考文獻(xiàn)：
    1. the presence of IL4I1 during T-cell activation decreases early signaling events downstream of t-cell receptor stimulation, resulting in global T-cell inhibition which is more pronounced when there is CD28 costimulation. PMID: 28891065
    2. Data showed proteome changes in alveolar epithelial cells type II exposed to an infection with A. fumigatus with IL4I1 showing the most prominent increase in abundance both, in terms of relative abundance as well as activity. Also, in the infected lungs, there was levels of IL4I1 metabolic products. PMID: 28951444
    3. reviewed SNPs of the IL4I1 isoform 1, which is expressed in lymphoid tissue; the N92D SNP leads to a hyperactive enzyme, while the R102G mutation is hypomorphic; show that IL4I1 activity is not only directed against phenylalanine, as initially described, but also at a lower level against arginine PMID: 26673964
    4. The immunosuppressive enzyme IL4I1 expressed differentially in human induced Aiolos+, but not natural Helios+, FOXP3+ Treg cells. PMID: 25446972
    5. IL4I1 upregulation in human Th17 cells limits their TCR-mediated expansion not only by blocking the molecular pathway involved in the activation of the IL-2 promoter, but also by maintaining high levels of Tob1, which impairs entry into the cell cycle. PMID: 24307243
    6. IL4I1 plays a distinct role compared to other antibacterial enzymes produced by mononuclear phagocytes. PMID: 23355881
    7. participates in the downregulation of Th1 inflammation PMID: 20683900
    8. genomic structure, cDNA sequence, chromosome location and RNA expression in immune tissues PMID: 12031486
    9. is activated in primary mediastinal large B-cell lymphoma, which might be due to a constitutive activation of a cytokine signaling pathway PMID: 12446450
    10. hIL4I1 inhibited the proliferation of CD3-stimulated T lymphocytes with a similar effect on CD4(+) and CD8(+) T cells. In contrast, memory T cells were more strongly affected by hIL4I1 and its catabolite H(2)O(2) than naive T cells PMID: 17356132
    11. strong IL4I1 expression is associated with B-cell lymphomas. PMID: 19436310
