Other Information

**Key Characteristics:** PLA2G7 is a member of the phospholipase A2 family, which consists of enzymes that hydrolyze ester bonds in phospholipids, leading to the production of bioactive lipid mediators. PLA2G7 exhibits a unique combination of high-density lipoprotein (HDL) particle-binding and calcium-independent phospholipase A2 activity, distinguishing it from other family members. This enzyme is predominantly expressed in cells of the immune system, including macrophages, dendritic cells, and epithelial cells, as well as in fetal tissues and neurons. **Pathways and Functions:** PLA2G7 is involved in various signaling pathways, including: 1. **Lipid Oxidation**: PLA2G7 catalyzes the hydrolysis of phospholipids, releasing arachidonic acid, which is then converted to eicosanoids, pro-inflammatory mediators. 2. **Inflammation**: The enzyme regulates the production of platelet-activating factor (PAF), a potent pro-inflammatory mediator that promotes leukocyte migration and activation. 3. **Antioxidant Defense**: PLA2G7 participates in the metabolism of oxidized phospholipids, which are generated during lipid peroxidation. 4. **Neuroprotection**: In the central nervous system, PLA2G7 is involved in the regulation of GABAergic signaling and the maintenance of neuronal homeostasis. **Clinical Significance:** PLA2G7 has been implicated in various diseases, including: 1. **Atherosclerosis**: Elevated PLA2G7 expression has been linked to the formation and progression of atherosclerotic plaques. 2. **Inflammatory Disorders**: Dysregulation of PLA2G7 has been observed in conditions such as rheumatoid arthritis, multiple sclerosis, and asthma. 3. **Neurodegenerative Diseases**: PLA2G7 has been implicated in the pathogenesis of Alzheimer's disease, Parkinson's disease, and other neurodegenerative disorders. 4. **Cancer**: The enzyme has been shown to contribute to cancer progression and metastasis, particularly in ovarian and breast cancers. In conclusion, PLA2G7 is a complex enzyme with diverse functions that underpin various physiological and pathological processes. Further research is needed to fully elucidate the mechanisms by which PLA2G7 regulates inflammation, lipid metabolism, and other cellular processes, with the ultimate goal of developing targeted therapies for the treatment of diseases associated with PLA2G7 dysregulation.

Database document:

This is a preview of the gene's schema. Only a few entries are kept for 'singleCellExpressions,' 'mRNAExpressions,' and other large data arrays for visualization purposes. You can zoom in with the mouse wheel for a closer view, and the text will adjust automatically if necessary. For the full schema, download it here.
