Function. ATP-dependent microtubule severing protein. Severs microtubules along their length and depolymerizes their ends, primarily the minus-end, that may lead to the suppression of microtubule growth from and attachment to centrosomes. Microtubule severing may promote rapid reorganization of cellular microtubule arrays and the release of microtubules from the centrosome following nucleation. Microtubule release from the mitotic spindle poles may allow depolymerization of the microtubule end proximal to the spindle pole, leading to poleward microtubule flux and poleward motion of chromosome.

Subunit / interactions. Interacts with AKAP8 (via C-terminus).

Subcellular location. Nucleus matrix. Cytoplasm. Cytoskeleton. Microtubule organizing center. Centrosome.

Similarity. Belongs to the AAA ATPase family.
