Schematic model of 12-LOX role in the regulation of FcγRIIa pathway. 12-LOX regulates early PLCγ2 activation mediated by FcγRIIa stimulation, which is essential for full calcium release in the platelets. Calcium flux is required for cPLA2 activity to generate free fatty acids, such as AA. Subsequently, Rap1 activation is also dependent on 12-LOX activity in order to activate integrin αIIbβ3 for platelet aggregation.
