Taxonomic identifier

44689 [NCBI]

Taxonomic lineage

Eukaryota › Amoebozoa › Mycetozoa › Dictyosteliida › Dictyostelium

Protein attributes

Sequence length	655 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	ATP-dependent microtubule severing protein. Microtubule severing may promote reorganization of cellular microtubule arrays and the release of microtubules from the microtubule organizing center following nucleation By similarity.
Catalytic activity	ATP + H2O = ADP + phosphate.
Subunit structure	Homohexamer. The homohexamer is stabilized by ATP-binding. The homohexamer may adopt a ring conformation through which microtubules pass prior to being severed. Interacts with microtubules By similarity.
Subcellular location	Membrane; Single-pass membrane protein Potential. Cytoplasm › cytoskeleton By similarity.
Sequence similarities	Belongs to the AAA ATPase family. Spastin subfamily. Contains 1 MIT domain.
