About LTA4H

Cytogenetic location: 12q23.1 Genomic coordinates (GRCh38): 12:96,000,753-96,043,520 (from NCBI)

This gene has 10 transcripts (splice variants), 207 orthologues and 11 paralogues. Ubiquitous expression in lung (RPKM 63.8), bone marrow (RPKM 53.7) and 25 other tissues.

Summary

The protein encoded by this gene is an Enzyme that contains both hydrolase and Aminopeptidase activities. The hydrolase activity is used in the final step of the biosynthesis of leukotriene B4, a proinflammatory mediator. The Aminopeptidase activity has been shown to degrade proline-glycine-proline (PGP), a neutrophil chemoattractant and biomarker for chronic obstructive pulmonary disease (COPD). Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2015]
