  • Target

    • Function
      Severs microtubules in vitro in an ATP-dependent manner. This activity may promote rapid reorganization of cellular microtubule arrays, such as during disassembly of interphase microtubules at the G2-M transition. May also be required for microtubule release from the centrosome after nucleation. In mitotic spindles this could allow depolymerization of the microtubule end proximal to the centrosome, and subsequent poleward microtubule flux. In neurons, microtubule release within the cell body may allow their subsequent transport into neuronal processes by microtubule dependent motor proteins. This transport is required for axonal growth.
    • Sequence similarities
      Belongs to the AAA ATPase family.
    • Domain
      The N-terminus is sufficient for interaction with microtubules, although high affinity binding requires an intact C-terminal domain and ATP, which promotes oligomerization.
    • Cellular localization
      Cytoplasm. Cytoplasm > cytoskeleton > centrosome. Cytoplasm > cytoskeleton > spindle pole. Predominantly cytoplasmic. Also localized to the interphase centrosome. Enhanced recruitment to the mitotic spindle poles requires microtubules and interaction with KATNB1.
