Septin-associated PIPKIγ splice variants drive centralspindlin association with the midbody via PI(4,5)P2

This study identifies septin-associated PIPKIγ splice variants as essential for midbody organization by generating PI(4,5)P2 required for centralspindlin recruitment and septin-microtubule association.

Multiscale imaging of cytokinesis

This study develops a multimodal imaging framework to analyze nanoscale reorganization of cytokinetic proteins during cell division, revealing a new substep and creating detailed molecular maps.

Condensates of synaptic vesicles and synapsin are molecular beacons for actin sequestering and polymerization

The paper investigates how synapsin-SV condensates organize presynaptic actin through LLPS, revealing their role in SV clustering and actin polymerization in lamprey and mammalian synapses.
