Cryo-EM structure of the ATP11C Q79E mutant reveals the structural basis for altered Phospholipid recognition.

Abstract excerpt

Closely related P4-ATPases, ATP11A and ATP11C, act as major phospholipid flippases in the plasma membrane of mammalian cells, with strict substrate specificity for phosphatidylserine (PS) and phosphatidylethanolamine (PE), but not for phosphatidylcholine (PC), thereby contributing to the asymmetric distribution of PS and PE across bilayers. A previously reported disease-associated Q84E mutation in ATP11A confers...
