found that microtubule polymerization depends on the amount of tubulin, the main microtubule component, on the presence of GTP, and on the absence of calcium. The proteins present in in vitro polymerized microtu-bules from brain extract have been characterized, and the presence of tubulin, a protein with a quaternary

The novel small molecule PTC596 directly binds tubulin, inhibits microtubule polymerization, downregulates MCL‐1, and induces p53‐independent apoptosis in acute myeloid leukemia cells. rupture. Microtubule polymerization and depolymerization decrease the overall axonal stiffness, but do not affect the evolution of damage at timescales relevant to axonal failure. Our study explains different failure mechanisms in the axon as emergent properties of microtubule polymerization, cross-link dynamics, and physical forces.

functions of the KISC complex on microtubule dynamics regulation. polymerize microtubules, an important event in plant morphogenesis.

2007-09-04 · In order to understand microtubule polymerization, it is useful to first present some details about the structure of these polymers. Microtubules are hollow cylinders of about 25 nm in diameter constructed from the protein tubulin. The outer diameter of a microtubule is between 23 and 27 nm while the inner diameter is between 11 and 15 nm.

This structural change seems to enable α-Synuclein to promote microtubule nucleation and folding and cause tubulin aggregation rather than polymerization.
