The γ-TuRC is recruited to microtubule-organizing centers by NEDD1. Muñoz-Hernández et al. report cryo-EM structures revealing how NEDD1’s C terminus forms an α-helical tetramer that docks onto the γ-TuRC without inducing major conformational changes in the complex, compatible with CDK5RAP2 binding and γ-tubulin ring closure.

Centriolar satellites are cytoplasmic particles found concentrated near centrosomes and the base of cilia in vertebrate cells whose functional contribution has long been unclear. Here, Pachinger et al. present a model for satellites not as transport modules but as sites of translation specifically of centrosomal and ciliary proteins.

This study provides insights into how cargo adaptors bind myosin V. Genetics, cell-based assays, cryo-EM, and AlphaFold reveal that the vacuole-specific adaptor uses a handhold mechanism to attach to two areas on the myosin-V tail. Moreover, evidence is presented that other adaptors use a similar strategy.

Human cells repair plasma membrane lesions in a two-step process. After a membrane scab forms at the lesion site, the scab is shed as annexin-containing extracellular vesicles.

The precise roles of the mitophagy receptors BNIP3 and NIX remain unclear. This study demonstrates that they are required for tight attachment and expansion of the isolation membrane along the mitochondrial surface, supporting a characteristic morphologic feature of the mitophagy.

This study examines how RIM and MUNC13 synergistically regulate DCV exocytosis. It demonstrates that MUNC13 is essential for DCV secretion, while RIM prevents its degradation. Key membrane-binding domains of RIM and MUNC13 play differing roles, revealing distinct mechanisms from synaptic vesicle release.

In mouse embryonic stem cells, the kinesin-13 member KIF2A converts from a microtubule depolymerase during metaphase to a microtubule stabilizer during cytokinesis, due to the inhibition of ATPase activity and a preference for compacted lattices. KIF2A-mediated microtubule stabilization prolongs cytokinesis to maintain stem cell pluripotency.
