WebJan 1, 2001 · Durstin M, Durstin S, Molski TF, Becker EL, Sha'afi RI. Cytoplasmic phospholipase A2 translocates to membrane fraction in human neutrophils activated by stimuli that phosphorylate mitogen-activated protein kinase. Proc Natl Acad Sci U S A. 1994 Apr 12; 91 (8):3142–3146. [PMC free article] [Google Scholar] WebCytosolic phospholipase A2 is an enzyme that in humans is encoded by the PLA2G4A gene. [5] [6] Function [ edit] This gene encodes a member of the cytosolic phospholipase A2 group IV family. The enzyme catalyzes the hydrolysis of membrane phospholipids to release arachidonic acid which is subsequently metabolized into eicosanoids.

Arachidonoyl-CoA is the precursor of archidonate in the plasma membrane, which is released by phospholipase A2. Acot7 overexpression might deplete the membrane of this eicosanoid precursor. Conversely, Acot7 itself might generate free arachidonic acid from arachidonoyl-CoA, or … dann white

WebApr 12, 1994 · In addition, the band that corresponds to phospholipase A2 is shifted upward in membrane isolated from neutrophils stimulated with fMet-Leu-Phe, suggesting that the enzyme has been altered, possibly phosphorylated, though not on tyrosine residues. A working hypothesis is presented. WebMar 3, 2006 · Abstract Phagocytosis of non-opsonized microorganisms by macrophages initiates innate immune responses for host defense against infection. Cytosolic phospholipase A (2) is activated during phagocytosis, releasing arachidonic acid for production of eicosanoids, which initiate acute inflammation. Increased phospholipase A 2 has also been associated with neuropsychiatric disorders such as schizophrenia and pervasive developmental disorders (such as autism), though the mechanisms involved are not known.
