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.
A cell-free reaction that reconstitutes the selective sorting of a miRNA into exosomes reveals an RNA-binding protein, YBX1, as a critical sorting factor.
Exosomes from cancer-associated fibroblasts enhance the "Warburg effect" in tumors and contain de novo metabolites that can contribute to the entire compendia of central carbon metabolism within cancer cells.
Plant-unique RAB5 effector 2 (PUF2) is an effector of plant-unique ARA6, which plays a key role in plant endosomal transport, integrating functions of the two plant RAB5 groups by an unprecedented mechanism.
An endosomal component employs a novel PAM2-like motif to recruit a key RNA-binding protein, which explains how mRNAs and associated ribosomes are attached to endosomes during coupled transport.
BLOS1 is a new regulator of LDLR endosomal recycling through coordinating kinesins during long-range transport, and depletion of BLOS1 in mouse liver leads to aberrant lipid metabolism.
Reconstitution of the endosomal Rab cascade reveals that Rab5 binds and activates the Mon1-Ccz1 guanine nucleotide exchange factor, which in turn recruits Rab7 to membranes to drive fusion.
