Nucleocytoplasmic regulation of microtubule-associated proteins. Model illustrating how microtubule-associated proteins in fission yeast are regulated in a spatiotemporal manner. Alp7/TACC-Alp14/TOG and Klp5-Klp6 (kinesin-8s) are targets of Ran in fission yeast and undergo nucleocytoplasmic shuttling during the cell cycle. Alp7-Alp14 is retained in the mitotic nucleus through inhibition of nuclear export by the cyclin-dependent kinase 1 (CDK1). See text for Klp5-Klp6 and Ase1. ‘I’ represents the destination of the protein in interphase, whereas ‘M’ is the destination in mitosis.
