    High resolution cryo-EM structure of the helical RNA-bound Hantaan virus nucleocapsid reveals its assembly mechanisms

    Benoît Arragain et al.
    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.

    Proteasome storage granules protect proteasomes from autophagic degradation upon carbon starvation

    Richard S Marshall, Richard D Vierstra
    Proteasomes are protected from autophagic elimination upon carbon starvation by sequestration into cytoplasmic storage granules, which aid cell fitness by providing a cache of proteasomes that can be rapidly remobilized when carbon availability improves.

    Cooperative interactions enable singular olfactory receptor expression in mouse olfactory neurons

    Kevin Monahan et al.
    Biochemical and genetic experiments show that Ebf and Lhx2 cooperate to specify olfactory receptor enhancers, which cooperate to drive olfactory receptor expression.
