WebJun 23, 2003 · During microtubule (MT) * assembly, hydrolysis of tubulin-bound GTP destabilizes the internal structure of a MT, eventually leading to a transition to shortening, termed a catastrophe. This switching between a growing and shortening state, which is referred to as dynamic instability, is important for a wide variety of cellular processes …
WebOct 13, 2024 · Previous studies demonstrated that nanomolar concentrations of nocodazole can block cells in mitosis without net microtubule disassembly and resulted in the hypothesis that this block was due to a nocodazole-induced stabilization of microtubules. We tested this hypothesis by examining the effects of nanomolar concentrations of nocodazole on … signs of hip infectionWebOct 4, 2024 · Microtubule dynamic instability. ( A) Microtubules are tubular filaments assembled from αβ-tubulin heterodimers arranged head-to-tail in 13 helically arranged protofilaments. Microtubules grow by the addition of GTP-tubulin (green) to their ends. GTP hydrolysis occurs when β-tubulin is buried in the lattice. signs of high pulse rateWebHome University of Colorado Boulder therapeutic radiation definitionWebThe dynamic behavior at the end of an individual microtubule is termed 'dynamic instability'.
