GeneID: 86



Names

Common Name: LTA4H Type: Gene
Chromosome: 12 (NC_000012.12) Locus: N/A
HUGO Symbol: LTA4H Full Name: leukotriene A4 hydrolase
Exons: 19 Introns: 18

Description:
The protein encoded by this gene is an enzyme that contains both epoxy hydrolase and aminopeptidase activities. The hydrolase site catalyses the conversion of the lipid substrate leukotriene A4 to the lipid proinflammatory mediator leukotriene B4. Leukotrienes are generated from arachidonic acid and LTA4H catalyses the final, rate limiting step in the synthesis of leukotriene B4. The aminopeptidase activity of LTA4H may be involved in the processing of peptides related to inflammation and host-defense. It has been shown to degrade the tri-amino acid peptide proline-glycine-proline (PGP), a known neutrophil chemoattractant and biomarker for chronic obstructive pulmonary disease (COPD). Polymorphisms in this gene associated with pulmonary hypertension in sickle cell patients. Several transcript variants encoding different isoforms have been found for this gene.
