Endocytic myosin-1 is a force-insensitive, power-generating motor
Pedersen, Snoberger et al. measure the force sensitivity of the yeast endocytic myosin-1 called Myo5 and find that it is m...
Tejas functions as a core component in nuage assembly and precursor processing in Drosophila piRNA biogenesis
Lin et al. report that Tejas, an essential component of piRNA pathway, plays a key role in recruiting Vasa (Vas) and Spind...
NME3 binds to phosphatidic acid and mediates PLD6-induced mitochondrial tethering
It is unclear whether and how mitochondrial fusion is selected. In this work, Su et al. demonstrate that NME3 functions as...
The minus-end depolymerase KIF2A drives flux-like treadmilling of γTuRC-uncapped microtubules
Henkin, Brito, et al. reconstitute in vitro a functional module elucidating previously poorly understood mechanisms of pol...
Mitochondrial double membrane fission: A mystery solved?
Westermann discusses two related studies examining a novel protein that plays a key role in mitochondrial division.

Competition for calnexin binding regulates secretion and turnover of misfolded GPI-anchored proteins
Misfolded GPI-APs are released from the ER to the Golgi for rapid degradation in lysosomes by the constitutively active an...
A nucleotide diphosphate kinase mediates tethering between mitochondria prior to fusion
Ikeda et al. highlight work from Su and colleagues that describes the mechanism by which NME3 and phosphatidic acid promot...
Nucleolar condensates: A cellular machinery necessary for T cell activation
Activated T cells boost ribosome production to meet their enormous protein synthesis demands. Sharma and Shaw discuss work...
Deep learning techniques and mathematical modeling allow 3D analysis of mitotic spindle dynamics
Spatial and temporal discontinuities in time-lapse movies frequently disrupt automation methods such as 3D object segmenta...
TLN1 contains a cancer-associated cassette exon that alters talin-1 mechanosensitivity
Gallego-Paez et al. identify a previously unannotated cassette exon in the TLN1 gene that alters the mechanical properties...
PP6 regulation of Aurora A–TPX2 limits NDC80 phosphorylation and mitotic spindle size
Chromosome alignment and segregation in mitosis are tightly regulated. This study shows that PP6 limits the activity of Au...
The exocyst complex is an essential component of the mammalian constitutive secretory pathway
Using kinetic trafficking assays, genetics, and secretomics, Pereira, Stalder et al. demonstrate the role of the exocyst c...
The meiotic LINC complex component KASH5 is an activating adaptor for cytoplasmic dynein
Dynein-driven chromosome movement facilitates chromosome synapsis in prophase I of meiosis, which is essential for genetic...
Productive HIV-1 infection of tissue macrophages by fusion with infected CD4 + T cells
Mascarau et al. demonstrate the relevance of HIV-1 infection of tissue-resident macrophages by fusion with infected CD4+ T...
ATG8-dependent LMX1B-autophagy crosstalk shapes human midbrain dopaminergic neuronal resilience
