Atomic force microscopy reveals a floppy, dimeric, coiled coil Golgin structure that captures transport vesicles via splayed, N-terminal ends at the Golgi complex.

We reveal TAPBPR is a peptide exchange catalyst which restricts the peptide repertoire presented by MHC I on cells, a finding which has important implications for all aspects of immune recognition.

Plasticity arising from autocatalytic receptor activation coexists with robustness in ligand responsiveness only by differential endosomal sorting of spontaneous and ligand-activated EGFR as distinct molecular states.
A nanomolar inhibitor of cholesterol transport out of endosomes/lysosomes can be crosslinked to the “sterol-sensing domain” of NPC1, which implicates this domain in the transmembrane transport of cholesterol.
Reconstitution of interleukin-1β secretion in non-macrophage cells implicates how this pro-inflammatory cytokine enters into the unconventional pathway of secretion through autophagy.
C. elegans germline stem cells become quiescent under starved conditions, and this quiescence maintains the stem cell state even in the absence of GLP-1/Notch signaling, which is otherwise essential for stem cell maintenance.

Experimentally reconstructing the evolution of the molecular complex that animals use to orient the mitotic spindle establishes a simple genetic and physical mechanism for the emergence of a function essential for multicellularity.
Nup98-HoxA9 is recruited to Hox gene cluster regions together with the chromosomally pre-bound nuclear export factor Crm1, which induces aberrant expression of several Hox genes and affecting the differentiation of embryonic stem cells.

A critical second step in DNA tethering by cohesin occurs after its stable binding to DNA, and this second step is modulated by the Smc3 ATPase active site in Saccharomyces cerevisiae.
Canonical centriole duplication is much less prone to errors than de novo synthesis of centrioles, but neither depends on self-oligomerization of the centriole protein SAS-6.
