Effect of S-100 protein on microtubule assembly-disassembly

Microtubule assembly and disassembly at alkaline pH

Although it is now apparent that the intracellular pH may rise considerably above neutrality under physiological conditions, information on the effect of alkaline pH on microtubule assembly and disassembly is still quite fragmentay. We have studied the assembly/disassembly of bovine brain microtubule protein at alkaline pH in vitro. When microtubules are assembled to a new steady state at pH le...

Microtubule-associated protein 2 alters the dynamic properties of microtubule assembly and disassembly.

The influence of microtubule-associated protein 2 (MAP2) on the dynamics of microtubule assembly and disassembly from axonemal fragments was characterized in vitro in solutions of pure tubulin and varying concentrations of MAP2. A mechanistic description of interactions between MAP2 and individual microtubules was developed from analysis of recorded images obtained by video-enhanced differentia...

A kinetic analysis of assembly-disassembly at opposite microtubule ends.

A Thermodynamic Model of Microtubule Assembly and Disassembly

Microtubules are self-assembling polymers whose dynamics are essential for the normal function of cellular processes including chromosome separation and cytokinesis. Therefore understanding what factors effect microtubule growth is fundamental to our understanding of the control of microtubule based processes. An important factor that determines the status of a microtubule, whether it is growin...
