Using a combination of PCR cloning and conventional screening procedures, we isolated from phorbol ester-treated mouse epidermis two full length cDNA clones encoding novel lipoxygenases. One of the cDNAs turned out to be identical to the recently cloned 8-lipoxygenase [Jisaka et al., J. Biol. Chem. 272 (1997) 24 410-24 416], the open reading frame of the second one corresponded to a protein of 701 amino acids with a calculated molecular mass of 80.6 kDa. The amino acid sequence showed 50.8% identity to human 15-lipoxygenase 2, approximately 40% to 5-lipoxygenase and 35% to 12- and 15-lipoxygenases. A unique structural feature is the insertion of 31 amino acid residues in the amino-terminal part of the molecule. Based on these data, we conclude that this epidermis-derived cDNA encodes a novel lipoxygenase isoform termed provisionally epidermis-type lipoxygenase 2 (e-LOX 2).
