- Dynamin-2 promotes myoblast fusion via actin bundling ability
The actin cytoskeleton drives formation of membrane protrusions that promote cell–cell fusion. Chuang et al. now find that the invadosome scaffold protein Tks5 is required for myoblast fusion. Tks5 regulates the assembly of dynamin-2 around actin bundles, thus strengthening the stiffness of the invadosome to propel cell–cell fusion.
- Translation factor mRNA localization and inheritance
Pizzinga et al. show that mRNAs encoding a range of translation factors are localized to granules that get transported into the yeast daughter cell using the She2p/She3p machinery. This likely supports an intensification of protein synthetic activity to facilitate apical polarized growth.
- The Wave complex suppresses Wnt–Sox9 signaling
The Wave complex promotes Arp2/3-mediated actin polymerization. Cohen et al. show that Wave complex activity regulates epidermal shape and growth. Without Wave complex activity, F-actin content is down-regulated and ectopic activity of the Wnt/β-catenin–SOX9 pathway is triggered. This activity induces epidermal hyperproliferation and disrupts tissue architecture.
- Mps2 and Mps3 form a noncanonical LINC
How the nuclear envelope is remodeled to facilitate insertion of large protein complexes is poorly understood. Chen et al. use superresolution imaging with bimolecular fluorescence complementation to show that a novel noncanonical linker of nucleoskeleton and cytoskeleton (LINC) complex forms at sites of nuclear envelope fenestration in yeast.
- Visualizing mitotic chromosome reorganization
Eykelenboom et al. track marked chromosome regions in live imaging of human cells with high spatial and temporal resolution to shed light on mitotic chromosome resolution and compaction dynamics.
- Secretory cargo transport during Golgi maturation
The Golgi cisternal maturation model predicts that secretory cargo proteins should be continuously present within the cisternae while resident Golgi proteins come and go. Casler et al. verify this prediction by tracking the passage of a fluorescent secretory cargo through the yeast Golgi.
- Secretory cargo transport within the Golgi
Kurokawa et al. visualize the transport of secretory cargo in the Golgi apparatus in living yeast cells. Cargo stays in the cisterna, whose property changes from cis to trans and further to the trans-Golgi network, but shows a dynamic behavior between the early and the late zones within the maturing cisterna.
