CC -!- FUNCTION: ATP-dependent microtubule severing protein. Stimulates
CC microtubule minus-end depolymerization and poleward microtubule flux in
CC the mitotic spindle. Regulates microtubule stability in the
CC neuromuscular junction synapse. Involved in lipid metabolism by
CC regulating the size and distribution of lipid droplets. Involved in
CC axon regeneration by regulating microtubule severing.
CC {ECO:0000255|HAMAP-Rule:MF_03021}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=n ATP + n H2O + a microtubule = n ADP + n phosphate + (n+1)
CC alpha/beta tubulin heterodimers.; EC=5.6.1.1;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03021};
CC -!- SUBUNIT: Homohexamer. The homohexamer is stabilized by ATP-binding. The
CC homohexamer may adopt a ring conformation through which microtubules
CC pass prior to being severed. Interacts with microtubules. Interacts
CC with atl; may be involved in microtubule dynamics. {ECO:0000255|HAMAP-
CC Rule:MF_03021}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255|HAMAP-Rule:MF_03021};
CC Peripheral membrane protein {ECO:0000255|HAMAP-Rule:MF_03021}.
CC Cytoplasm, cytoskeleton, microtubule organizing center, centrosome
CC {ECO:0000255|HAMAP-Rule:MF_03021}. Cytoplasm, cytoskeleton
CC {ECO:0000255|HAMAP-Rule:MF_03021}. Chromosome {ECO:0000255|HAMAP-
CC Rule:MF_03021}. Lipid droplet {ECO:0000255|HAMAP-Rule:MF_03021}.
CC Note=Forms an intramembrane hairpin-like structure in the membrane.
CC Colocalizes with cellular microtubule arrays. Localizes to chromosomes
CC from prometaphase/metaphase to anaphase, and this requires
CC microtubules. Localizes to discrete punctate cytoplasmic foci which may
CC correspond to secretory vesicles. {ECO:0000255|HAMAP-Rule:MF_03021}.
CC -!- SIMILARITY: Belongs to the AAA ATPase family. Spastin subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_03021}.
