Copper is a trace element required to maintain essential life processes. In healthy organisms, copper metabolism is well balanced. If this balance is destroyed, the cellular level of free copper might increase and cause toxic effects. So far, the molecular mechanisms of copper intoxication are understood only partly. The present study revealed that the kinesin-dependent transport system is...
This study investigated the hypothesis that the chromosomal genotoxicity of inorganic mercury results from interaction(s) with cytoskeletal proteins. Effects of Hg2+ salts on functional activities of tubulin and kinesin were investigated by determining tubulin assembly and kinesin-driven motility in cell-free systems. Hg2+ inhibits microtubule assembly at concentrations above 1 µM, and inhibition...
