Modeling mitosis.
The mitotic spindle is a fascinating protein machine that uses bipolar arrays of dynamic microtubules and many mitotic motors to coordinate the accurate segregation of sister chromatids. Here we discuss recent mathematical models and computer simulations that, in concert with experimental studies, help explain the molecular mechanisms by which the spindle machinery performs its crucial function...
متن کاملMitosis sans Mitosis: The Mitotic Oscillator in Differentiation.
Differentiation and proliferation are usually considered to be antagonistic partners in development. However, in a recent issue of Science, Al Jord et al. (2017) show that key regulators of the mitotic cycle are redeployed in differentiating multiciliated cells to promote ciliogenesis without mitotic progression.
متن کاملMitosis: KLP61F Goes Wee!
Kinesin-5s help assemble the bipolar spindle by crosslinking and sliding apart antiparallel microtubules. A recent study has uncovered a novel pathway for the phospho-regulation of these motors.
متن کاملMitosis is swell
Cell volume and dry mass are typically correlated. However, in this issue, Zlotek-Zlotkiewicz et al. (2015. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201505056) and Son et al. (2015. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201505058) use new live-cell techniques to show that entry to mitosis coincides with rapid cell swelling, which is reversed before division.
متن کاملMitosis without wind
From nuclear pore to kinetochore uclear proteins are turning up in some odd places lately. First, the nuclear-transport factor Ran was implicated in spindle formation. Then, the mitotic checkpoint proteins Mad1 and Mad2 turned up at the nuclear pore, in a switch with the mRNA export factor hRae1, which appeared with the mitotic checkpoint protein mBUB1 at the kinetochore. Now, Belgareh et al. r...
