WebJun 1, 2024 · Key to these functions is the fact that microtubules are "dynamic." As with actin, the polymer dynamics are driven by nucleotide hydrolysis and influenced by a host of specialized regulatory proteins, including microtubule-associated proteins. However, microtubule turnover involves a surprising behavior-termed dynamic instability-in which ... WebAug 15, 2012 · Dynamic instability is an essential phenomenon in eukaryotic nuclear division and prokaryotic plasmid R1 segregation. Although the molecular machines used …
WebMar 26, 2024 · The highly ramified arbors of neuronal dendrites provide the substrate for the high connectivity and computational power of the brain. Altered dendritic morphology is associated with neuronal diseases. Many molecules have been shown to play crucial roles in shaping and maintaining dendrite morphology. Yet, the underlying principles by which … WebWe have developed video microscopy methods to visualize the assembly and disassembly of individual microtubules at 33-ms intervals.

WebMicrotubules are highly dynamic and will frequently grow and shrink at a rapid yet constant rate. During this phenomenon, known as ‘dynamic instability’, tubulin subunits will both associate and dissociate from the … WebThe Journal of Cell Biology Dynamic instability regulated by force Janson et al. 1031 down as the amplitude of buckling increases, and the force can thus be considered constant during buckling. The growth velocity resulting from this force was derived from a linear fit to the MT length data (Fig. 2 A, inset). This proce-
