Function
Secretory calcium-dependent phospholipase A2 that primarily targets extracellular phospholipids (PubMed:10681567, PubMed:11922621, PubMed:28883454). Hydrolyzes the ester bond of the fatty acyl group attached at sn-2 position of phospholipids (phospholipase A2 activity), releasing various unsaturated fatty acids including oleoate, linoleoate, arachidonate, docosahexaenoate and lysophosphatidylethanolamines in preference to lysophosphatidylcholines (PubMed:10681567, PubMed:28883454). In response to high-fat diet, hydrolyzes minor lipoprotein phospholipids including phosphatidylserines, phosphatidylinositols and phosphatidylglycerols, altering lipoprotein composition and fat storage in adipose tissue and liver (By similarity). May act in an autocrine and paracrine manner (PubMed:11922621). Contributes to lipid remodeling of cellular membranes and generation of lipid mediators involved in pathogen clearance. Cleaves sn-2 fatty acyl chains of phosphatidylglycerols and phosphatidylethanolamines, which are major components of membrane phospholipids in bacteria (PubMed:11922621). Acts as a hair follicle phospholipase A2. Selectively releases lysophosphatidylethanolamines (LPE) and various unsaturated fatty acids in skin to regulate hair follicle homeostasis (By similarity). May regulate the inflammatory response by releasing arachidonate, a precursor of prostaglandins and leukotrienes (PubMed:11922621). Upon allergen exposure, may participate in allergic inflammatory response by enhancing leukotriene C4 synthesis and degranulation in mast cells (By similarity).

- Activity summary
Secretory phospholipase A2 group IIE (sPLA2-IIE) is an enzyme belonging to the phospholipase A2 family also known as PLA2G2E. It has a molecular mass of approximately 14 kDa. sPLA2-IIE hydrolyzes the sn-2 position of glycerophospholipids releasing free fatty acids and lysophospholipids. This enzyme shows expression in various tissues including the pancreas and inflammatory sites where it contributes to lipid metabolism and cell membrane remodeling.
- Biological function summary
Secretory phospholipase A2 group IIE plays a role in inflammation and immune responses. Its activity results in the production of arachidonic acid and lysophospholipids which are precursors for eicosanoids like prostaglandins and leukotrienes. These lipid mediators regulate inflammatory processes thereby altering cellular responses. sPLA2-IIE participates in a complex network of enzymes and receptors modulating lipid signaling and affecting diverse physiological functions.
- Pathways
SPLA2-IIE interacts within the arachidonic acid pathway and the eicosanoid biosynthesis pathway. In these pathways sPLA2-IIE generates bioactive lipids impacting inflammatory signaling. It functions alongside proteins such as cyclooxygenase (COX) and lipoxygenase (LOX) which further metabolize arachidonic acid into specific eicosanoids. These pathways illustrate the enzyme's contribution to finely tuning the inflammatory response and cellular signaling networks.
- Associated diseases and disorders
Secretory phospholipase A2 group IIE associates with conditions like rheumatoid arthritis and atherosclerosis. Its enzymatic activity correlates with the inflammatory components of these diseases promoting tissue damage and disease progression. Through its involvement in lipid mediator synthesis sPLA2-IIE interacts with proteins like interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) key players in the inflammatory pathways that drive these disorders. Understanding the role of sPLA2-IIE in these diseases can help develop targeted therapies.
