Mechanisms of chromosome congression during mitosis

H Maiato, AM Gomes, F Sousa, M Barisic - Biology, 2017 - mdpi.com
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

RA Cross, A McAinsh - Nature reviews Molecular cell biology, 2014 - nature.com
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

J Kajtez, A Solomatina, M Novak, B Polak… - Nature …, 2016 - nature.com
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

M Jagrić, P Risteski, J Martinčić, A Milas, IM Tolić - Elife, 2021 - elifesciences.org
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

MW Elting, CL Hueschen, DB Udy, S Dumont - Journal of Cell Biology, 2014 - rupress.org
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 …

Mechanobiology of the mitotic spindle

N Pavin, IM Tolić - Developmental cell, 2021 - cell.com
The mitotic spindle is a microtubule-based assembly that separates the chromosomes
during cell division. As the spindle is basically a mechanical micro machine, the …

PRC 1‐labeled microtubule bundles and kinetochore pairs show one‐to‐one association in metaphase

B Polak, P Risteski, S Lesjak, IM Tolić - EMBO reports, 2017 - embopress.org
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 …
