HGNC Family | C2 domain containing, Phospholipases |
Name | phospholipase A2, group IVD (cytosolic) |
Description | The phospholipase A2 enzyme family, including PLA2G4D, catalyze the hydrolysis of glycerophospholipids at the sn-2 position and then liberate free fatty acids and lysophospholipids (Chiba et al., 2004 [PubMed 14709560]).[supplied by OMIM, Jun 2009] |
Summary |
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nPLA2G4D, a member of the cytosolic phospholipase A₂ family, plays a critical role in inflammatory skin disorders such as psoriasis. Studies have shown that PLA2G4D is highly expressed in psoriatic lesions, where its calcium‐dependent lipolytic activity promotes the generation of neolipid antigens. In one report, PLA2G4D was detected in mast cells and, surprisingly, found to be active extracellularly via exosome release induced by interferon‐α. This extracellular activity facilitates the transfer of PLA2G4D to neighboring antigen‐presenting CD1a⁺ cells, thereby triggering the activation of lipid‐reactive T cells that produce IL-17A and IL-22. Another study confirmed that PLA2G4D (also termed cPLA₂δ) is preferentially expressed in stratified squamous epithelia and is markedly upregulated in the upper spinous layer of psoriatic epidermis, implicating it in the local inflammatory response."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIn addition to its role in inflammatory skin disease, PLA2G4D has been identified as one of several recurrently mutated genes in splenic marginal zone lymphoma (SMZL).
