  • 產(chǎn)品描述：

    LTA4H, an enzyme that converts LTA4 to LTB4, regulates the balance between the anti-inflammatory lipoxins and pro-inflammatory LTB4, with direct implications for TB-driven inflammation. In addition to its epoxide hydrolase activity, LTA4H also possesses anion-dependent aminopeptidase activity. As an aminopeptidase, LTA4H degrades the N-terminus of peptides. The aminopeptidase activity of LTA4H is generally assumed to be involved in the processing of peptides related to inflammation and host defense and may be involved in human cancer. Overexpression of LTA4H has been found in several human cancers including skin cancer.

    The vectors expressing anti-LTA4H antibody were constructed as follows: immunizing an animal with A synthesized peptide derived from human LTA4H, isolating the positive splenocyte and extracting RNA, obtaining DNA by reverse transcription, sequencing and screening LTA4H antibody gene, and amplifying heavy and light chain sequence by PCR and cloning them into plasma vectors. After that, the vector clones were transfected into the mammalian cells for production. The product is the recombinant LTA4H antibody. Recombinant LTA4H antibody in the culture medium was purified using Affinity-chromatography. It can react with LTA4H protein from Human, Mouse and is used in the ELISA, WB.

靶點詳情

  • 功能：
    Bifunctional zinc metalloenzyme that comprises both epoxide hydrolase (EH) and aminopeptidase activities. Acts as an epoxide hydrolase to catalyze the conversion of LTA4 to the proinflammatory mediator leukotriene B4 (LTB4). Has also aminopeptidase activity, with high affinity for N-terminal arginines of various synthetic tripeptides. In addition to its proinflammatory EH activity, may also counteract inflammation by its aminopeptidase activity, which inactivates by cleavage another neutrophil attractant, the tripeptide Pro-Gly-Pro (PGP), a bioactive fragment of collagen generated by the action of matrix metalloproteinase-9 (MMP9) and prolylendopeptidase (PREPL). Involved also in the biosynthesis of resolvin E1 and 18S-resolvin E1 from eicosapentaenoic acid, two lipid mediators that show potent anti-inflammatory and pro-resolving actions.

    1. The structures reveal that a single catalytic water is involved in both catalytic activities of LTA4H, alternating between epoxide ring opening and peptide bond hydrolysis, assisted by E271 and E296, respectively. Moreover, we have found two conformations of LTA4H, uncovering significant domain movements. PMID: 28827365
    2. A higher incidence of severe IRIS among patients with mutant LTA4H genotypes (CT and TT) was observed compared to the wild type, despite similar IRIS incidence and immune restoration in both groups. Steroids were effective in alleviating IRIS in all the genotypes PMID: 27643598

    4. LTA4H genotype predicted survival of HIV-uninfected patients, with TT-genotype patients significantly more likely to survive tuberculous meningitis than CC-genotype patients.

LTA4H genotype may predict adjunctive corticosteroid responsiveness in HIV-uninfected individuals. PMID: 28419368
