Protein
Katanin p60 ATPase-containing subunit A1
Organism
Strongylocentrotus purpuratus
Function
Catalytic subunit of a complex which severs microtubules in an ATP-dependent manner. Microtubule severing may promote rapid reorganization of cellular microtubule arrays and the release of microtubules from the centrosome following nucleation. In mitotic spindles this could allow depolymerization of the microtubule end proximal to the centrosome, and subsequent poleward microtubule flux.
Similarity
Belongs to the AAA ATPase family. Katanin p60 subunit A1 subfamily.
