Kinetochore connects centromeric chromatin to microtubules during mitosis. Surprisingly, kinetochore proteins were found in postmitotic Drosophila neurons. When these proteins were knocked down, the number of growing plus ends in the dendrites of uninjured neurons increased, leading to the conclusion that kinetochore suppresses microtubule dynamics in dendrites by regulating nucleation. Overexpression and RNAi knockdown of various kinetochore proteins will determine whether any genes in centromeric DNA participate in the regulation of microtubule dynamics.
