Cell Division: MAST Sails Through Mitosis
Successful mitosis requires coordinated activities of microtubules and numerous associated proteins. A recent study implicates the microtubule-associated protein MAST/Orbit in a surprisingly wide array of mitotic activities, ranging from maintaining mitotic spindle bipolarity to tethering chromosomes to the ends of microtubules.
متن کاملObservations on Cell Growth, Mitosis, and Division in the Fungus Basidiobolus Ranarum
The paper describes the forward streaming, growth, and division of the vegetative cell of Basidiobolus ranarum. The cell is several hundred microns long and has a single large nucleus. Mitosis is invariably followed by cell division. Both processes have been studied in the living cell by ordinary and phase contrast microscopy. Mitosis is accompanied by a temporary coarsening of the organisation...
متن کاملArabidopsis TANGLED Identifies the Division Plane throughout Mitosis and Cytokinesis
BACKGROUND In premitotic plant cells, the future division plane is predicted by a cortical ring of microtubules and F-actin called the preprophase band (PPB). The PPB persists throughout prophase, but is disassembled upon nuclear-envelope breakdown as the mitotic spindle forms. Following nuclear division, a cytokinetic phragmoplast forms between the daughter nuclei and expands laterally to atta...
متن کاملThe Mammalian Golgi Regulates Numb Signaling in Asymmetric Cell Division by Releasing ACBD3 during Mitosis
Mammalian neural progenitor cells divide asymmetrically to self-renew and produce a neuron by segregating cytosolic Numb proteins primarily to one daughter cell. Numb signaling specifies progenitor over neuronal fates but, paradoxically, also promotes neuronal differentiation. Here we report that ACBD3 is a Numb partner in cell-fate specification. ACBD3 and Numb proteins interact through an ess...
