Common NamePA(8:0/22:0)
DescriptionPA(8:0/22:0) 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(8:0/22:0), in particular, consists of one chain of caprylic acid at the C-1 position and one chain of behenic acid at the C-2 position. Phosphatidic acids are quite rare but are extremely important as intermediates in the biosynthesis of triacylglycerols and phospholipids.

Enzymes

General function:
Involved in protein binding
Specific function:
May have a role in signal-induced cytoskeletal regulation and/or endocytosis (By similarity).
Gene Name:
PLD2
Uniprot ID:
O14939
Molecular weight:
104656.485
General function:
Involved in diacylglycerol kinase activity
Specific function:
Phosphorylates diacylglycerol (DAG) to generate phosphatidic acid (PA). May regulate the activity of protein kinase C by controlling the balance between these two signaling lipids. Activated in the nucleus in response to alpha-thrombin and nerve growth factor. May be involved in cAMP- induced activation of NR5A1 and subsequent steroidogenic gene transcription by delivering PA as ligand for NR5A1. Acts synergistically with NR5A1 on CYP17 transcriptional activity
Gene Name:
DGKQ
Uniprot ID:
P52824
Molecular weight:

Reverses the normal flow of glycerolipid biosynthesis by phosphorylating diacylglycerol back to phosphatidic acid
Gene Name:
DGKG
Uniprot ID:
P49619
Molecular weight:
89095.3
General function:
Involved in catalytic activity
Specific function:
Catalyzes the conversion of phosphatidic acid (PA) to diacylglycerol (DG). In addition it hydrolyzes lysophosphatidic acid (LPA), ceramide-1-phosphate (C-1-P) and sphingosine-1-phosphate (S-1-P). The relative catalytic efficiency is PA > C-1-P > LPA > S-1-P.
Gene Name:

General function:
Involved in diacylglycerol kinase activity
Specific function:
Upon cell stimulation converts the second messenger diacylglycerol into phosphatidate, initiating the resynthesis of phosphatidylinositols and attenuating protein kinase C activity
Gene Name:
DGKA
Uniprot ID:
P23743
Molecular weight:

General function:
Involved in diacylglycerol kinase activity
Specific function:
Isoform 2 may be involved in cell growth and tumorigenesis. Involved in clathrin-dependent endocytosis
Gene Name:
DGKD
Uniprot ID:
Q16760
Molecular weight:
134524.2
General function:
Involved in catalytic activity
Specific function:
Broad-specificity phosphohydrolase that dephosphorylates exogenous bioactive glycerolipids and sphingolipids. Catalyzes the conversion of phosphatidic acid (PA) to diacylglycerol (DG). Pivotal regulator of lysophosphatidic acid (LPA) signaling in the cardiovascular system. Major enzyme responsible of dephosphorylating LPA in platelets, which terminates signaling actions of LPA. May control circulating, and possibly also regulate localized, LPA levels resulting from platelet activation. It has little activity towards ceramide-1-phosphate (C-1-P) and sphingosine-1-phosphate (S-1-P). The relative catalytic efficiency is LPA > PA > S-1-P > C-1-P. It's down-regulation may contribute to the development of colon adenocarcinoma.
