Fly protein families Dprs and DIPs can create a multitude of complementary interfaces for homo- and heterophilic adhesion complexes, resulting in instructive roles for connectivity in the motor neuron circuitry.
Single-molecule FRET experiments reveal that G40P, a DnaB-like helicase, unwinds double-stranded DNA in single base pair steps and its processivity is enhanced by host primase DnaG.
Hantaan virus nucleocapsid cryo-EM structure determined at 3.3 Å resolution reveals how nucleoproteins assemble into a metastable helix containing a continuous RNA-binding groove compatible with genome encapsidation and compaction.
Phase separated DNA-free stored forms of RecA dissolve in response to DNA damage to make RecA available for repair and recombination reactions as part of the bacterial (Escherichia coli) SOS response.
Correlative microscopy and electron cryo-tomography on apoptotic HeLa cells reveal remodeling of outer and inner mitochondrial membranes, Bax cluster ultrastructure and ATP synthase reorganization in ruptured mitochondria.
Computational modeling of a dynamin-constricted membrane neck can rank proposed shape changes of the helical scaffold in terms of their fission aptitude and elucidate the associated pathways.
Structures of a TMEM16 phospholipid scramblase reveal that its Ca2+-dependent activation entails global conformational changes and how these rearrangements affect the membrane to enable transbilayer lipid transfer.
Meiotic chromosome axis 'core' proteins from fungi, plants, and mammals form a conserved filament architecture, and use a common mechanism to recruit HORMAD proteins for meiotic recombination control.
A functionally conserved inactivation gate in the inner helix of Piezo channels controls the majority of the inactivation process via a hydrophobic mechanism.
