Hydrogen-deuterium exchange, electron microscopy, and vesicle reconstitution show how binding of the autophagy adaptor NDP52 to the FIP200 subunit of the ULK1 complex triggers membrane binding in autophagy.

Building on previous work (Vogel et al., 2013b), it is shown that myosin-driven actin filament rearrangements actively move, split or fuse individual lipid domains and change their overall shape.
Activation of the sarcoplasmic reticulum calcium pump and enhancement of cellular calcium homeostasis by dwarf open reading frame reveal how this small membrane protein opposes phospholamban inhibitory function in cardiac muscle.
A reconstituted system has been developed that self-organizes into dynamic actin cortices capable of spontaneous polarization, similar to the initial cortical polarization observed in cells during embryogenesis and development.
The dynamic structure of respiratory complex I from mesophilic bacterium is revealed and demonstrates existence of uncoupled conformations in the bacterial complex.
During neurotransmitter release, calcium-induced membrane insertion of the C2B domain of Synaptotagmin re-orients the bound SNARE complex which dilates the fusion pore in a mechanical lever action.
