Mechanisms of chromosome congression during mitosis
Chromosome congression during prometaphase culminates with the establishment of a
metaphase plate, a hallmark of mitosis in metazoans. Classical views resulting from more …

Prime movers: the mechanochemistry of mitotic kinesins
Mitotic spindles are self-organizing protein machines that harness teams of multiple force
generators to drive chromosome segregation. Kinesins are key members of these force …

Overlap microtubules link sister k-fibres and balance the forces on bi-oriented kinetochores
During metaphase, forces on kinetochores are exerted by k-fibres, bundles of microtubules
that end at the kinetochore. Interestingly, non-kinetochore microtubules have been observed …

Optogenetic control of PRC1 reveals its role in chromosome alignment on the spindle by overlap length-dependent forces
During metaphase, chromosome position at the spindle equator is regulated by the forces
exerted by kinetochore microtubules and polar ejection forces. However, the role of forces …

Microtubule poleward flux in human cells is driven by the coordinated action of four kinesins
Y Steblyanko, G Rajendraprasad, M Osswald… - The EMBO …, 2020 - embopress.org
Mitotic spindle microtubules (MT s) undergo continuous poleward flux, whose driving force
and function in humans remain unclear. Here, we combined loss‐of‐function screenings …

Force on spindle microtubule minus ends moves chromosomes
The spindle is a dynamic self-assembling machine that coordinates mitosis. The spindle's
function depends on its ability to organize microtubules into poles and maintain pole …

PRC 1‐labeled microtubule bundles and kinetochore pairs show one‐to‐one association in metaphase
In the mitotic spindle, kinetochore microtubules form k‐fibers, whereas overlap or interpolar
microtubules form antiparallel arrays containing the cross‐linker protein regulator of …

Shaping up to divide: coordinating actin and microtubule cytoskeletal remodelling during mitosis
OM Lancaster, B Baum - Seminars in cell & developmental biology, 2014 - Elsevier
Cell division requires the wholesale reorganization of cell architecture. At the same time as
the microtubule network is remodelled to generate a bipolar spindle, animal cells entering …
