Mammalian cells contain multiple structurally different phospholipase A2 enzymes that hydrolyse sn-2 fatty acid from membrane phospholipid. The low molecular weight secreted forms act extracellularly both as lipolytic enzymes and as agonists that bind to specific cell surface receptors.

Journal of Lipid Mediators and Cell Signalling, 1995
To summarize the regulation of cPLA2, we have proposed a model for the activation of cPLA2 based both on our previous studies (Clark et al., 1991; Lin et al., 1993) and the work of many others (Fig. 5). In this model, cPLA2 is tightly regulated by multiple pathways, including those that control Ca2+ concentration, phosphorylation states and cPLA2 ...

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2004
Phospholipase A2 (PLA2) is an enzyme present in snake and other venoms and body fluids. We measured PLA2 catalytic activity in tissue homogenates of 22 species representing the classes Anthozoa, Hydrozoa, Scyphozoa and Cubozoa of the phylum Cnidaria. High PLA2 levels were found in the hydrozoan fire coral Millepora sp.

Phospholipase A2 (PLA2) catalytic activity was measured in aqueous extracts of 83 freeze-dried specimens representing 55 marine sponge species collected from the east coast of Australia including the Great Barrier Reef. High levels (>500 u/l) of PLA2 activity (defined as the amount of activity that releases 1 micromol of fatty acid per min) were found ...

Prostaglandins & Other Lipid Mediators, 2002
Phospholipase A2 (PLA2) catalyzes the hydrolysis of the sn-2 position of membrane glycerophospholipids to liberate arachidonic acid (AA), a precursor of eicosanoids including prostaglandins and leukotrienes. The same reaction also produces lysophosholipids, which represent another class of lipid mediators.

Current Opinion in Lipidology, 2009
As the role of lipids and inflammation in the genesis and progression of the atherosclerosis disease is unquestionable, novel treatment modalities that target both aspects are currently under investigation.For a long time atherosclerosis was regarded as a lipid-driven disease, but now it is evident that it also involves the simultaneous and combined ...

Lipoprotein-Associated Phospholipase A2 [PDF]
Clinics in Laboratory Medicine, 2006 Lipoprotein-associated phospholipase A2 (LP-PLA2) is an emerging inflammatory marker that is used to assess the risk for cardiovascular disease (CVD) and associated events. Several epidemiologic studies have demonstrated an independent association between plasma Lp-PLA2 concentration and risk for cardiovascular events.

Phospholipase A2 receptor: a regulator of biological functions of secretory phospholipase A2
Prostaglandins & Other Lipid Mediators, 2002The phospholipase A2 receptor (PLA2R) is a type I transmembrane glycoprotein related to the C-type animal lectin family that includes the mannose receptor. PLA2R regulates a variety of biological responses elicited by specific types of secretory PLA2s (sPLA2s).

Extracellular Phospholipase A2
1992Various lipids have been implicated in signal transduction and as precursors of lipid mediators, among them arachidonic acid (Dennis et al., 1991). Production of the prostaglandins, thromboxanes, and prostacyclins via the cyclooxygenase pathway, as well as the production of the leukotrienes and lipoxins via the lipoxygenase pathway, all depend on the ...

Polarographic assay for phospholipase A2
Analytical Biochemistry, 1980Abstract A rapid, specific, and quantitative assay for phospholipase A2 from Naja naja venom has been devised, in which phospholipid hydrolysis is measured as soybean lipoxidase-catalyzed oxygen incorporation into the ensuing unsaturated fatty acids. Under conditions where phospholipid was limiting, a linear relationship developed between the extent ...
