This gene is a member of the secretory phospholipase A2 family. It is located in a tightly-linked cluster of secretory phospholipase A2 genes on chromosome 1. The encoded enzyme catalyzes the hydrolysis of membrane phospholipids to generate lysophospholipids and free fatty acids including arachidonic acid. It preferentially hydrolyzes linoleoyl-containing phosphatidylcholine substrates. Secretion of this enzyme is thought to induce inflammatory responses in neighboring cells. Alternatively spliced transcript variants have been found, but their full-length nature has not been determined. [provided by RefSeq, Jul 2008]

Among its related pathways are Ras signaling pathway and PAK Pathway. GO annotations related to this gene include calcium ion binding and calcium-dependent phospholipase A2 activity. An important paralog of this gene is PLA2G2D.
UniProtKB/Swiss-Prot for PLA2G5 Gene
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. This isozyme hydrolyzes more efficiently L-alpha-1-palmitoyl-2-oleoyl phosphatidylcholine than L-alpha-1-palmitoyl-2-arachidonyl phosphatidylcholine, L-alpha-1-palmitoyl-2-arachidonyl phosphatidylethanolamine, or L-alpha-1-stearoyl-2-arachidonyl phosphatidylinositol. May be involved in the production of lung surfactant, the remodeling or regulation of cardiac muscle
Phospholipases are a group of enzymes that hydrolyze phospholipids into fatty acids and other lipophilic molecules. PLA is subdivided into PLA1 which cleave phospholipids at the sn-1 ester bond and PLA2, which cleave at the sn-2 bond. Their most common substrate is phosphatidylcholine, which generates lysophosphatidylcholine and arachidonic acid. PLA is regulated by phosphorylation and by intracellular Ca2+ concentrations. Phospholipases are ubiquitously expressed and have diverse biological functions including roles in inflammation, cell growth, signaling and death and maintenance of membrane phospholipids.
