Common NamePE(DiMe(9,5)/MonoMe(9,5))
DescriptionPE(DiMe(9,5)/MonoMe(9,5)) is a phosphatidylethanolamine (PE or GPEtn). It is a glycerophospholipid in which a phosphorylethanolamine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, glycerophosphoethanolamines can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. Fatty acids containing 16, 18 and 20 carbons are the most common. PE(DiMe(9,5)/MonoMe(9,5)), in particular, consists of one chain of 10,13-epoxy-11,12-dimethyloctadeca-10,12-dienoic at the C-1 position and one chain of 10,13-epoxy-11-methyloctadeca-10,12-dienoic at the C-2 position. The 10,13-epoxy-11,12-dimethyloctadeca-10,12-dienoic moiety is derived from fish oil, while the 10,13-epoxy-11-methyloctadeca-10,12-dienoic moiety is derived from fish oil. Phospholipids, are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling. While most phospholipids have a saturated fatty acid on C-1 and an unsaturated fatty acid on C-2 of the glycerol backbone, the fatty acid distribution at the C-1 and C-2 positions of glycerol within phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. PEs are neutral zwitterions at physiological pH. They mostly have palmitic or stearic acid on carbon 1 and a long chain unsaturated fatty acid (e.g. 18:2, 20:4 and 22:6) on carbon 2. PE synthesis can occur via two pathways. The first requires that ethanolamine be activated by phosphorylation and then coupled to CDP. The ethanolamine is then transferred from CDP-ethanolamine to phosphatidic acid to yield PE. The second involves the decarboxylation of PS.

Enzymes

General function:
Involved in phospholipase A2 activity
Specific function:
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. This isozyme hydrolyzes more efficiently L-alpha-1-palmitoyl-2-oleoyl phosphatidylcholine than L-alpha-1-palmitoyl-2-arachidonyl phosphatidylcholine, L-alpha-1-palmitoyl-2-arachidonyl phosphatidylethanolamine, or L-alpha-1-stearoyl-2-arachidonyl phosphatidylinositol. May be involved in the production of lung surfactant, the remodeling or regulation of cardiac muscle.

Gene Name:
PLA2G2F
Uniprot ID:
Q9BZM2
Molecular weight:
23256.29
General function:
Involved in metabolic process
Specific function:
Selectively hydrolyzes arachidonyl phospholipids in the sn-2 position releasing arachidonic acid. Together with its lysophospholipid activity, it is implicated in the initiation of the inflammatory response.
Gene Name:
PLA2G4A
Uniprot ID:
P47712
Molecular weight:
85210.19
General function:
Involved in phospholipase A2 activity
Specific function:
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides.
Gene Name:
PLA2G1B
Uniprot ID:
P04054
Molecular weight:
16359.535
General function:
Involved in phospholipase A2 activity
Specific function:
Not known; does not seem to have catalytic activity.
Gene Name:
PLA2G12B
Uniprot ID:
Q9BX93
Molecular weight:
Not Available
General function:
Involved in phospholipase A2 activity
Specific function:
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. Has a powerful potency for releasing arachidonic acid from cell membrane phospholipids. Prefers phosphatidylethanolamine and phosphatidylcholine liposomes to those of phosphatidylserine.
Gene Name:
PLA2G10
Uniprot ID:
O15496
Molecular weight:
18153.04
General function:
Involved in phospholipase A2 activity
Specific function:
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. Has a preference for arachidonic-containing phospholipids.
Gene Name:
PLA2G2E
Uniprot ID:
Q9NZK7
Molecular weight:
15988.525
General function:
Involved in metabolic process
Specific function:
Catalyzes the release of fatty acids from phospholipids. It has been implicated in normal phospholipid remodeling, nitric oxide-induced or vasopressin-induced arachidonic acid release and in leukotriene and prostaglandin production. May participate in fas mediated apoptosis and in regulating transmembrane ion flux in glucose-stimulated B-cells. Has a role in cardiolipin (CL) deacylation. Required for both speed and directionality of monocyte MCP1/CCL2-induced chemotaxis through regulation of F-actin polymerization at the pseudopods. Isoform ankyrin-iPLA2-1 and isoform ankyrin-iPLA2-2, which lack the catalytic domain, are probably involved in the negative regulation of iPLA2 activity.
Gene Name:
PLA2G6
Uniprot ID:
O60733
Molecular weight:
84092.635
General function:
Involved in phospholipase A2 activity
Specific function:
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. L-alpha-1-palmitoyl-2-linoleoyl phosphatidylethanolamine is more efficiently hydrolyzed than the other phospholipids examined.
Gene Name:
PLA2G2D
Uniprot ID:

Molecular weight:
16546.1
General function:
Involved in protein binding
Specific function:
May have a role in signal-induced cytoskeletal regulation and/or endocytosis (By similarity).
