Spindle assembly is spatially regulated by a chromosome-derived Ran- GTP gradient. Previous work proposed that Ran-GTP activates spindle assembly factors (SAFs) around chromosomes by dissociating inhibitory importins from SAFs. However, it is unclear whether the Ran-GTP gradient equivalently activates SAFs
