Common NamePA(18:0/18:2(9Z,12Z))
DescriptionPA(18:0/18:2(9Z,12Z)) is a phosphatidic acid. It is a glycerophospholipid in which a phosphate moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidic acids 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. PA(18:0/18:2(9Z,12Z)), in particular, consists of one chain of stearic acid at the C-1 position and one chain of linoleic acid at the C-2 position. The stearic acid moiety is derived from animal fats, coco butter and sesame oil, while the linoleic acid moiety is derived from seed oils. Phosphatidic acids are quite rare but are extremely important as intermediates in the biosynthesis of triacylglycerols and phospholipids. Indeed, the concentration of phosphatidic acids is often over-estimated in tissues and biofluids as it can arise by inadvertent enzymatic hydrolysis during inappropriate storage or extraction conditions during analysis. The main biosynthetic route of phosphatidic acid in animal tissues involves sequential acylation of alpha-glycerophosphate by acyl-CoA derivatives of fatty acids. PAs are biologically active lipids that can stimulate a large range of responses in many different cell types, such as platelet aggregation, smooth muscle contraction, in vivo vasoactive effects, chemotaxis, expression of adhesion molecules, increased tight junction permeability of endothelial cells, induction of stress fibres, modulation of cardiac contractility, and many others. Diacylglycerols (DAGs) can be converted to PAs by DAG kinases and indirect evidence supports the notion that PAs alter the excitability of neurons. Phospholipase Ds (PLDs), which catalyze the conversion of glycerolphospholipids, particularly phosphatidylcholine, to PAs and the conversion of N-arachidonoyl-phosphatidylethanolamine (NAPE) to anandamide and PAs are activated by several inflammatory mediators including bradykinin, ATP and glutamate. PAs activate downstream signaling pathways such as PKCs and mitogen-activated protein kinases (MAPKs), which are linked to an increase in sensitivity of sensory neurons either during inflammation or in chronic pain models. Circumstantial evidence that PAs are converted to DAGs. (PMID: 12618218 , 16185776 ).

Hydrolyzes lysophosphatidic acid (LPA). Facilitates axonal outgrowth during development and regenerative sprouting. In the outgrowing axons acts as an ecto-enzyme and attenuates phospholipid-induced axon collapse in neurons and facilitates outgrowth in the hippocampus.
Gene Name:
LPPR4
Uniprot ID:
Q7Z2D5
Molecular weight:
76553.42
General function:
Involved in catalytic activity
Specific function:
Not Available
Gene Name:
LPPR5
Uniprot ID:
Q32ZL2
Molecular weight:
35427.1
General function:
Involved in catalytic activity
Specific function:
Phosphatase that dephosphorylates presqualene diphosphate (PSDP) into presqualene monophosphate (PSMP), suggesting that it may be indirectly involved in innate immunity. PSDP is a bioactive lipid that rapidly remodels to presqualene monophosphate PSMP upon cell activation. Displays diphosphate phosphatase activity with a substrate preference for PSDP > FDP > phosphatidic acid
Gene Name:
PPAPDC2
Uniprot ID:
Q8IY26
Molecular weight:
32193.2
General function:
Involved in catalytic activity
Specific function:
Plays a role as negative regulator of myoblast differentiation, in part through effects on MTOR signaling. Has no detectable enzymatic activity
Gene Name:
PPAPDC3
Uniprot ID:
Q8NBV4
Molecular weight:
29447.3
General function:
Involved in catalytic activity
Specific function:
Displays magnesium-independent phosphatidate phosphatase activity in vitro. Catalyzes the conversion of phosphatidic acid to diacylglycerol.
Gene Name:
PPAPDC1A
Uniprot ID:
Q5VZY2
Molecular weight:
30394.27
General function:
Involved in catalytic activity
Specific function:
Displays magnesium-independent phosphatidate phosphatase activity in vitro. Catalyzes the conversion of phosphatidic acid to diacylglycerol. May be a metastatic suppressor for hepatocellular carcinoma.
