Cell division is essential to the propagation of life. During cell division, mitotic spindles segregate duplicated chromosomes with high fidelity. Spindle structure depends on the proper polar ...

Cumulative evidence supports the idea that a gradient of Ran controls the mitotic spindle assembly. During mitosis, RCC1 associates with chromosomes, generating a gradient of RanGTP around chromosomes ...

The spindle-assembly checkpoint (SAC) is a safety device that monitors the attachment of spindle microtubules to the surface of chromosome-associated structures called kinetochores. It is believed ...

Mechanistic model for MTOC maturation in GV oocytes. The MTOC (grey) activates near the oocyte cortex, which requires recruitment of CKAP5 and TACC3. After activation, MTOC migrates to the nuclear ...
