Identification of a heparan sulfate proteoglycan with a dedicated function in unconventional protein secretion reveals an intimate relationship between fibroblast growth factor 2 and Glypican-1 in cancer biology.
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.

The tissue growth controlling Hippo signalling pathway is modulated by the activity of the Casein Kinase 1 family, which regulates the protein stability of the upstream Hippo pathway component Expanded.
The Munc18-1 protein promotes formation of the t-SNARE complex and the half-zippered SNARE complex, two rate-limiting steps of SNARE assembly, to enhance membrane fusion.
The structure of gp41with its membrane anchors highlights the flexible linkage of the transmembrane regions and the fuson peptides, which generates an asymmetric conformation, a potential target of MPER bNAbs.
The formation of HIV-1 particles requires a bending of the membrane that cannot be achieved by the Gag protein alone and thus there is need for the I-BAR protein IRSp53 to aid in the formation of HIV-1 buds.
