| Antigen: rabbit reticulocyte 15-LO · Host: sheep · Application(s): WB; other applications not tested · 15-Lipoxygenase-1 (15-LO-1) catalyzes the formation of 15(S)-HETE and 13(S)-HODE from arachidonic acid and linoleic acid, respectively.1,2 15-LO-1 is a monomer with a molecular mass of approximately 75 kDa and is found primarily in reticulocytes and eosinophils.2,3,4 Interleukin-4 and -13 induce the expression of 15-LO-1 mRNA in human monocytes.5,6 The induction of 15-LO-1 by both agents is inhibited by IFNγ.5,6 A second 15-LO, 15-LO-2, cloned from human hair roots, has been identified.7 15-LO-2 exhibits approximately 40% identity to the 15-LO-1 and is expressed in prostate, lung, and cornea. |
