Super-resolution microscopy reveals focal organization of ER-associated Y-complexes in mitosis.

During mitotic entry of vertebrate cells, nuclear pore complexes (NPCs) are rapidly disintegrated. NPC disassembly is initiated by hyperphosphorylation of linker nucleoporins (Nups), which leads to the dissociation of FG repeat Nups and relaxation of the nuclear permeability barrier. However, less is known about disintegration of the huge nuclear and cytoplasmic rings, which are formed by annular assemblies of Y-complexes that are dissociated from NPCs as intact units.

Kinesin-14 motors drive a right-handed helical motion of antiparallel microtubules around each other.

Within the mitotic spindle, kinesin motors cross-link and slide overlapping microtubules.
