Building on previous work (Tang et al., 2015), novel ESCRT-III subunit Snf7 auto-activation mutants are used to reveal two parallel ubiquitin-dependent pathways during multivesicular endosome biogenesis.
Large-volume light microscopy combined with higher-resolution electron tomography revealed the spatial distribution of virus-producing cells and highlighted mechanisms of HIV-1 dissemination in bone marrow from a small animal model.
Structural and biochemical studies indicate that AAA+ ATPase employ a general mechanism to translocate a variety of substrates, including extended polypeptides, hairpins, crosslinked chains, and chains conjugated to other molecules.
A Drosophila fertility gene is identified that acts as a linker between HP1a and local H3K4 demethylation during HP1a-mediated gene silencing that is required for ovary development and transposon silencing..
Quantitative 3D lattice light sheet microscopy of unperturbed cells combined with electron tomography and acute loss of function experiments reveals how dynamic ESCRT-III/Vps4 assemblies succeed in reverse membrane budding on endosomes.
