Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Functions as 15-oxo-prostaglandin 13-reductase and acts on 15-oxo-PGE1, 15-oxo-PGE2 and 15-oxo-PGE2-alpha. Has no activity towards PGE1, PGE2 and PGE2-alpha. Catalyzes the conversion of leukotriene B4 into its biologically less active metabolite, 12-oxo-leukotriene B4. This is an initial and key step of metabolic inactivation of leukotriene B4 By similarity.
Catalytic activity	n-alkanal + NAD(P)+ = alk-2-enal + NAD(P)H. 11-alpha-hydroxy-9,15-dioxoprost-5-enoate + NAD(P)+ = (5Z)-(13E)-11-alpha-hydroxy-9,15-dioxoprosta-5,13-dienoate + NAD(P)H.
Subunit structure	Monomer or homodimer By similarity.
Subcellular location	Cytoplasm By similarity.
Induction	Up-regulated by 1,2-dithiole-3-thione (D3T). Ref.1
Sequence similarities	Belongs to the NADP-dependent oxidoreductase L4BD family.
