Zusammenfassung: | Polyglycerophospholipids (PGPLs) such as bismonoacylglycerophosphate (BMP) and cardiolipin are important membrane phospholipid species for the maintenance of membrane integrity. While BMP serves as membrane curvature regulator in multivesicular bodies for efficient lysosomal enzyme function, cardiolipin stabilizes the electron transfer complex in the inner mitochondrial membrane, which is crucial for physiological ATP production. Beside their membrane modulatory functions PGPLs play an important role in various signaling events. Although a number of disease associations were found for PGPL species, detailed information about their molecular role still remains unknown. This article reviews the known biological functions of PGPLs and the existing mass spectrometric methods. We discuss the different analytical strategies and how ESI–MS/MS can expand our understanding of PGPL homeostasis. |
