CC   -!- FUNCTION: Catalyzes the regio and stereo-specific incorporation of
CC       molecular oxygen into free and esterified polyunsaturated fatty acids
CC       generating lipid hydroperoxides that can be further reduced to the
CC       corresponding hydroxy species (PubMed:8188678, PubMed:11256953,
CC       PubMed:25293588). Mainly converts arachidonate ((5Z,8Z,11Z,14Z)-
CC       eicosatetraenoate) to the specific bioactive lipid (12S)-
CC       hydroperoxyeicosatetraenoate/(12S)-HPETE (PubMed:8188678,
CC       PubMed:11256953). Through the production of bioactive lipids like
CC       (12S)-HPETE it regulates different biological processes including
CC       platelet activation (PubMed:9501222). It can also catalyze the
CC       epoxidation of double bonds of polyunsaturated fatty acids such as
CC       (14S)-hydroperoxy-docosahexaenoate/(14S)-HPDHA resulting in the
CC       formation of (13S,14S)-epoxy-DHA. Furthermore, it may participate in
CC       the sequential oxidations of DHA ((4Z,7Z,10Z,13Z,16Z,19Z)-
CC       docosahexaenoate) to generate specialized pro-resolving mediators
CC       (SPMs) like resolvin D5 ((7S,17S)-diHPDHA) and (7S,14S)-diHPDHA, that
CC       actively down-regulate the immune response and have anti-aggregation
CC       properties with platelets (By similarity). An additional function
CC       involves a multistep process by which it transforms leukotriene A4/LTA4
CC       into the bioactive lipids lipoxin A4/LXA4 and lipoxin B4/LXB4, both are
CC       vasoactive and LXA4 may regulate neutrophil function via occupancy of
CC       specific recognition sites (By similarity). Can also peroxidize
CC       linoleate ((9Z,12Z)-octadecadienoate) to (13S)-
CC       hydroperoxyoctadecadienoate/ (13S-HPODE) (PubMed:11256953). Due to its
CC       role in regulating both the expression of the vascular endothelial
CC       growth factor (VEGF, an angiogenic factor involved in the survival and
CC       metastasis of solid tumors) and the expression of integrin beta-1
CC       (known to affect tumor cell migration and proliferation), it can be
CC       regarded as protumorigenic. Important for cell survival, as it may play
CC       a role not only in proliferation but also in the prevention of
CC       apoptosis in vascular smooth muscle cells (By similarity).

CC       Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC       Note=Binds 1 Fe cation per subunit.;
CC   -!- ACTIVITY REGULATION: Activated by EGF. Arachidonic acid conversion is
CC       inhibited by (13S,14S)-epoxy-(4Z,7Z,9E,11E,16Z,19Z)-docosahexaenoate
CC       (13S,14S-epoxy-DHA) (By similarity). Arachidonate 12-lipoxygenase
CC       activity is decreased when PH decreases from 7.4 to 6
CC       (PubMed:11256953). {ECO:0000250|UniProtKB:P18054,
CC       ECO:0000269|PubMed:11256953}.
CC   -!- PATHWAY: Lipid metabolism; hydroperoxy eicosatetraenoic acid
CC       biosynthesis.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol {ECO:0000269|PubMed:7868854}.
CC       Membrane {ECO:0000250}. Note=Membrane association is stimulated by EGF.
CC       {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Found primarily in platelets and in microsomal and
CC       cytosolic fractions of the epidermis (at protein level).
CC       {ECO:0000269|PubMed:10383730, ECO:0000269|PubMed:8188678,
CC       ECO:0000269|PubMed:9501222}.
CC   -!- DISRUPTION PHENOTYPE: Mice are fertile and appear to exhibit no gross
CC       abnormalities. However, they display increased aggregation of platelets
CC       in response to ADP. They also display a mild basal transepidermal water
CC       loss. {ECO:0000269|PubMed:10383730, ECO:0000269|PubMed:9501222}.
CC   -!- SIMILARITY: Belongs to the lipoxygenase family. {ECO:0000305}.
