WebJul 1, 2016 · During model testing, an intense dynamic instability was observed (a); no vibration occurred before 1 second but a sharp peak at the natural vibration frequency was obtained (b); and violent self-excited vibration of the gate was induced (c). Model experiment of friction-maintained dynamic stability WebJan 5, 1999 · Dynamic instability is presumed to be the major mechanism of MT turnover and allows MTs to explore intracellular space (6). An alternative mechanism of MT turnover recently has been described for microsurgically produced cytoplasmic fragments of melanophores lacking the centrosome (7). WebMar 16, 2015 · Proper modelling of dynamic instability is a crucial tool to understand the mechanism of action of microtubule targeting agents. In this paper, we propose a new concept for GTP-tubulin hydrolysis which allow the model to accurately reproduce microtubule dynamics observed in vitro or in cells.
