Lysophospholipase PNPLA7 is a critical checkpoint of phosphatidylcholine catabolism and turnover for skeletal muscle homeostasis.
Current evidence suggests that disturbed phosphatidylcholine (PC) turnover causes skeletal muscle dysfunction. However, the enzyme that converts lysophosphatidylcholine (LPC) to glycerophosphocholine (GPC), an irreversible checkpoint in PC catabolism, in skeletal muscle has remained unidentified. Here we show that PNPL...
