sSgo1, a guardian of centriole cohesion

Sgo1 plays a key role in protecting sister chromatid cohesion during mitosis. In this issue of Developmental Cell, Wang et al. describe a shorter splice variant of Sgo1 (sSgo1) that functions specifically in centriole cohesion. sSgo1 may be the glue that holds paired centrioles together in an engaged state before their disengagement in late mitosis.
