Protein Variants

EC Number Protein Variants Comment Organism
3.3.2.6 additional information mutations in the leukotriene A4 hydrolase gene result in decreased lta4h mRNA expression and increased susceptibility to Mycobacterial infection. lta4h mutations confer hypersusceptibility independent of LTB4 reduction, by redirecting eicosanoid substrates to anti-inflammatory lipoxins. The resultant anti-inflammatory state permits increased mycobacterial proliferation by limiting production of tumor necrosis factor. Lta4h deficiencies result in an immunoregulatory phenotype, overview. Two single-nucleotide polymorphisms are rs1978331 and rs2660898, overview Homo sapiens
3.3.2.6 additional information screening for mutagenized zebrafish larvae phenotypes that differ in their ability to control the replication of Mycobacterium marinum, overview. Three classes of mutants that are hypersusceptible to Mycobacterium marinum infection, one of which mapps to the lta4h locus. The phenotype is not reversible by addition of exogenous LTB4. Induced lta4h deficiency in either wild-type or mutant larvae compromises neither mycobacterially-induced recruitment to the hindbrain ventricle nor bacterial phagocytosis. Lta4h deficiency compromises TNF induction and phenotypically resembles TNF signaling deficiency Danio rerio
