Mending microtubules enhances cell polarity

Abstract

Microtubule repair has recently emerged as a mechanism that is capable of enhancing the longevity of microtubules. In this issue of Developmental Cell, Andreu-Carbó et al. show that the microtubule motor kinesin-1 can create a cycle of microtubule damage and repair that is sufficient to bring about changes in cell polarity.
