Summaries for SPAST Gene

Entrez Gene Summary for SPAST Gene

  • This gene encodes a member of the AAA (ATPases associated with a variety of cellular activities) protein family. Members of this protein family share an ATPase domain and have roles in diverse cellular processes including membrane trafficking, intracellular motility, organelle biogenesis, protein folding, and proteolysis. The encoded ATPase may be involved in the assembly or function of nuclear protein complexes. Two transcript variants encoding distinct isoforms have been identified for this gene. Other alternative splice variants have been described but their full length sequences have not been determined. Mutations associated with this gene cause the most frequent form of autosomal dominant spastic paraplegia 4. [provided by RefSeq, Jul 2008]

GeneCards Summary for SPAST Gene

SPAST (Spastin) is a Protein Coding gene. Diseases associated with SPAST include spastic paraplegia 4, autosomal dominant and spastic paraplegia 4. GO annotations related to this gene include microtubule binding and four-way junction helicase activity. An important paralog of this gene is FIGN.

UniProtKB/Swiss-Prot for SPAST Gene

  • ATP-dependent microtubule severing protein. Microtubule severing may promote reorganization of cellular microtubule arrays and the release of microtubules from the centrosome following nucleation. Required for membrane traffic from the endoplasmic reticulum (ER) to the Golgi and for completion of the abscission stage of cytokinesis. May also play a role in axon growth and the formation of axonal branches.

    Size:
    616 amino acids
    Molecular mass:
    67197 Da
    Quaternary structure:
    • Homohexamer. Mostly monomeric, but assembles into hexameric structure for short periods of time. Oligomerization seems to be a prerequisite for catalytic activity. Binding to ATP in a cleft between two adjacent subunits stabilizes the homohexameric form. Binds to microtubules at least in part via the alpha-tubulin and beta-tubulin tails. The hexamer adopts a ring conformation through which microtubules pass prior to being severed. Does not interact strongly with tubulin heterodimers. Interacts (via MIT domain) with CHMP1B; the interaction is direct. Interacts with ATL1, RTN1, SSNA1 and ZFYVE27. Isoform 1 but not isoform 3 interacts with RTN2. Interacts with REEP1.

UniProtKB/Swiss-Prot BiophysicochemicalProperties:
Kinetic parameters: KM=0.45 mM for ATP {ECO:0000269 PubMed:15716377, ECO:0000269 PubMed:17389232, ECO:0000269 PubMed:22637577}; Vmax=1.2 nmol/min/ug enzyme {ECO:0000269 PubMed:15716377, ECO:0000269 PubMed:17389232, ECO:0000269 PubMed:22637577}; Note=Kinetic parameters shown are for full length enzyme. N- terminally truncated spastin (residues 228-616), which has been shown to exhibit full severing activity, shows a basal ATP turnover rate of 0.78 sec(-1) in the absence of microtubules, a KM of 0.16 mM for ATP, and the ATP turnover rate is extrapolated to 3.83 sec(-1) in the presence of microtubules. ATPase activity shows non-Michaelis-Menten kinetics in the presence of microtubules, but is close to non-cooperative behavior in their absence (PubMed:22637577). {ECO:0000269 PubMed:22637577};
UniProtKB/Swiss-Prot CatalyticActivity:
ATP + H(2)O = ADP + phosphate.
UniProtKB/Swiss-Prot EnzymeRegulation:
Allosteric enzyme with a cooperative mechanism; at least two neighbor subunits influence each other strongly in spastin hexamers. Microtubule binding promotes cooperative interactions among spastin subunits.
UniProtKB/Swiss-Prot Function:
ATP-dependent microtubule severing protein. Microtubule severing may promote reorganization of cellular microtubule arrays and the release of microtubules from the centrosome following nucleation. Required for membrane traffic from the endoplasmic reticulum (ER) to the Golgi and for completion of the abscission stage of cytokinesis.

  • Spastic paraplegia 4, autosomal dominant (SPG4) [MIM:182601]: A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. {ECO:0000269 PubMed:10610178, ECO:0000269 PubMed:10699187, ECO:0000269 PubMed:11015453, ECO:0000269 PubMed:11039577, ECO:0000269 PubMed:11087788, ECO:0000269 PubMed:11309678, ECO:0000269 PubMed:11843700, ECO:0000269 PubMed:11985387, ECO:0000269 PubMed:12124993, ECO:0000269 PubMed:12161613, ECO:0000269 PubMed:12163196, ECO:0000269 PubMed:12202986, ECO:0000269 PubMed:12460147, ECO:0000269 PubMed:12552568, ECO:0000269 PubMed:12939659, ECO:0000269 PubMed:14732620, ECO:0000269 PubMed:15159500, ECO:0000269 PubMed:15210521, ECO:0000269 PubMed:15248095, ECO:0000269 PubMed:15326248, ECO:0000269 PubMed:15482961, ECO:0000269 PubMed:16682546, ECO:0000269 PubMed:16684598, ECO:0000269 PubMed:17594340, ECO:0000269 PubMed:18613979, ECO:0000269 PubMed:20214791, ECO:0000269 PubMed:20550563, ECO:0000269 PubMed:20562464, ECO:0000269 PubMed:20718791, ECO:0000269 PubMed:20932283}.
