Cytosolic phospholipase A2 (cPLA2) is a calcium-sensitive 85-kDa enzyme, that hydrolyzes arachidonic acid-containing membrane phospholipids to, initiate the biosynthesis of eicosanoids and platelet-activating factor, potent inflammatory mediators. The calcium-dependent activation of the, enzyme is mediated by an N-terminal C2 domain, which is responsible for, calcium-dependent translocation of the enzyme to membranes and that, enables the intact enzyme to hydrolyze membrane-resident substrates. The, 2.4-A x-ray crystal structure of this C2 domain was solved by multiple, isomorphous replacement and reveals a beta-sandwich with the same topology, as the C2 domain from phosphoinositide-specific phospholipase C delta 1., Two clusters of exposed hydrophobic residues surround two adjacent ...

== Function ==
 +
[https://www.uniprot.org/uniprot/PA24A_HUMAN PA24A_HUMAN] 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.
