PLA2G15 is a BMP hydrolase and its targeting ameliorates lysosomal disease - Nature
Briefly

Lysosomes play a critical role in cellular waste removal, nutrient recycling, and maintaining cellular homeostasis by breaking down complex lipids. A unique lipid called bis(monoacylglycero)phosphate (BMP) enhances lysosomal lipid metabolism and is associated with various diseases, notably age-related neurodegeneration, cancer, and cardiovascular issues. Despite identifying lysosomal BMP synthase, questions remain about BMP degradation mechanisms. Understanding the catabolism of BMP, influenced by its unique stereochemistry, is essential for therapeutic developments. Recent studies indicate that the phospholipase A2 enzyme may play a role in BMP hydrolysis, highlighting the complex dynamics of lipid metabolism in lysosomes.
Understanding the unique structure and metabolism of bis(monoacylglycero)phosphate (BMP) is crucial for elucidating its role in lysosomal functions and disease implications.
BMP significantly enhances lysosomal lipid metabolism, and its imbalance is linked to various lysosome-associated diseases such as cancer and cardiovascular disease.
