Microtubule-associated protein complex consisting of transforming acidic coilded coil (TACC) protein Mia1p/Alp7p accumulates in the nucleus at mitotic entry and is restricted to the cytoplasm during interphase. Accumulation of Mia1p upon mutation of a carboxy-terminus NES leads to severe microtubule abnormalities at multiple stages of the cell cycle. Cells containing a mutant allele of CRM1, CRM1-809, showed nuclear accumulation of Mia1p at the restrictive temperature of 18°C but not at 36°C. Absence of the Mia1p NES leads to abnormalities in mitotic spindle organization, which is indicative of microtubule/kinetochore interaction and metaphase delay.
A partner of Mia1p, Alp14p/TOG colocalizes with Mia1p in the nuclei of CRM1-809 cells at 18°C, suggesting the entire TACC/TOG complex shuttles between the nucleus and cytoplasm. The mutation of the NES in Mia1p compromise its binding to Alp14/TOG, but artificial accumulation of Alp14/TOG can rescue some effects of the Mia1p NES mutation.

Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus.
Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb
by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
