PLA2G2D Protein, Mouse (HEK293, Fc)

PLA2G2D Protein is a secretory calcium-dependent phospholipase A2 that primarily targets extracellular lipids, exerting anti-inflammatory and immunosuppressive functions. It hydrolyzes the ester bond of the fatty acyl group attached at the sn-2 position of phospholipids, with a preference for phosphatidylethanolamines and phosphatidylglycerols over phosphatidylcholines. In draining lymph nodes, it selectively hydrolyzes diacyl and alkenyl forms of phosphatidylethanolamines, releasing omega-3 polyunsaturated fatty acids (PUFAs) such as eicosapentaenoate and docosahexaenoate, which are precursors of the anti-inflammatory lipid mediators known as resolvins. During the resolution phase of acute inflammation, PLA2G2D Protein drives the synthesis of resolvin D1 derived from docosahexaenoate, which suppresses dendritic cell activation and T-helper 1 immune response. In addition to its catalytic activity, PLA2G2D Protein promotes the differentiation of regulatory T cells (Tregs) and participates in the maintenance of immune tolerance. It may also contribute to lipid remodeling of cellular membranes and the generation of lipid mediators involved in pathogen clearance. Moreover, PLA2G2D Protein displays bactericidal activity against Gram-positive bacteria by directly hydrolyzing phospholipids of the bacterial membrane.
