Deskripsi

The heterodimeric eukaryotic Drs2p-Cdc50p complex is a lipid flippase that maintains cell membrane asymmetry and its autoinhibition is released by PI4P binding. Here authors show cryo-EM structures of Drs2p-Cdc50p in apo and PI4P-activated form which reveal the structural changes upon PI4P binding.
