  • Review Article |

    This Review describes the various mechanisms of ion-coupled transport across membranes and how the activities of transporter proteins are modulated by the composition of the lipid bilayer.

    The cellular organelles peroxisomes contribute to the sensitivity of cells to ferroptosis by synthesizing polyunsaturated ether phospholipids, and changes in the abundances of these lipids are associated with altered sensitivity to ferroptosis during cell-state transitions.

    Cryo-electron microscopy structures of heterodimeric and homodimeric full-length GABAB receptors, combined with cellular signalling assays, shed light on the mechanisms that underpin signal transduction mediated by these receptors.

    A mechanism for phosphoinositide conversion at endosomes to enable exit from the endosomal system, suggesting that defective phosphoinositide conversion at endosomes underlies X-linked centronuclear myopathy.

    Mfsd2a is the major transporter of the omega-3 fatty acid docosahexaenoic acid (DHA) into brain, with Mfsd2a-knockout mice showing reduced DHA in brain, neuronal cell loss in hippocampus and cerebellum, behavioural disorders and reduced brain size; DHA is transported in a sodium-dependent manner, in the form of lysophosphatidylcholines (LPCs) carrying long-chain fatty acids.

    Lipid asymmetry can be disrupted during biological processes such as apoptosis, during which phosphatidylserine in the inner leaflet of the membrane is exposed on the outer membrane. It has been proposed that activation of a phospholipid scramblase catalyses bidirectional transbilayer movement of phospholipids, but the protein corresponding to this activity has not been identified. Here, the protein TMEM16F is identified, and is an essential component for the Ca2+-dependent exposure of phosphatidylserine on the plasma membrane. A patient with Scott syndrome, which results from a defect in phospholipid scrambling activity, was found to carry a mutation in the gene encoding TMEM16F.
