The role of spindle during mitosis
Webb16 juli 2012 · The mitotic spindle, a microtubule-based structure, is required for chromosome segregation during cell division. Motor proteins are molecular machines that utilise the energy of adenosine triphosphate (ATP) hydrolysis to move along microtubules. WebbThe mitotic spindle has long been known to play a crucial role in mitosis, orchestrating the segregation of chromosomes into two daughter cells during mitosis with high fidelity. …

WebbFör 1 dag sedan · Spindly has been reported to be involved in rapid integration of peripheral chromosomes into the mitotic spindle but not as such in chromosome attachment to microtubules (Barisic et al., 2010). Moreover, Spindly is involved in the prevention of load-bearing attachment formation during prometaphase in C. elegans ( Gassmann et al., … Webb11 apr. 2024 · PLK1 is an important regulator of mitosis whose protein levels and activity fluctuate during the cell cycle. PLK1 dynamically localizes to various mitotic structures to regulate chromosome segregation. However, the signaling pathways linking localized PLK1 activity to its protein stability remain elusive.
WebbSpindle fibres constitute mitotic and meiotic spindle during cell division. They are formed by microtubules and play an important role during nuclear division.
