Patronin Takes a Shot at Polarity

摘要

To specify the anterior-posterior axis of Drosophila embryos, noncentrosomal microtubules grow out from cortical regions of the oocyte and help transport axis determinants. In this issue of Developmental Cell, Nashchekin et al. (2016) report a Shot- and Patronin-dependent mechanism by which the oocyte cortex produces polarized microtubule arrays.
