12-OxoETE is synthesized by human platelets and Aplysia nervous tissue after incubation with arachidonic acid. Microsomal fractions of various tissues will reduce 12-oxoETE to 12(S)-HETE or a mixture of 12(S)- and 12(R)-HETE. 12-OxoETE induces a rapid, dose dependent increase of cytoplasmic free calcium via an Leukotriene B4 receptor or a common activation sequence.
