Discovery that actin moves chromosomes changes fundamental thinking
August 4th, 2005
Microtubules need a helping hand to find chromosomes in dividing egg cells, scientists have discovered. Although it was generally accepted that microtubules act alone as the cellular ropes to pull chromosomes into place, a new study by researchers at the European Molecular Biology Laboratory (EMBL) shows that this is not the case. They found that in large cells such as animal eggs, something else is needed to move the chromosomes into the correct location - fibers of the cytoskeletal molecule actin (Nature, online July 13, 2005). "No one has ever shown that actin moves chromosomes," said Dr. Jan Ellenberg, the EMBL researcher whose group...
