Function
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.
Catalytic activity
Activity regulation
ATPase activity is stimulated by microtubules, which promote homooligomerization. ATP-dependent microtubule severing is stimulated by interaction with KATNB1.
