Entry term(s) proteína 4 de la paraplejia espástica
Scope note: ATPasa AAA que se une a los MICROTÚBULOS y los corta. Específicamente reconoce y corta los microtúbulos poliglutamilados con colas cortas de poliglutamato para favorecer la reorganización de las matrices de microtúbulos celulares y la liberación de los microtúbulos del CENTROSOMA tras la nucleación. Se trata de una enzima crítica para la biogénesis y el mantenimiento de matrices complejas de microtúbulos en los AXONES, el HUSO MITÓTICO y los CILIOS. Las mutaciones en el gen de la espastina (SPAST) se asocian con el tipo 4 de la PARAPLEJIA ESPÁSTICA HEREDITARIA.

Scope note: An AAA ATPase that binds and severs MICROTUBULES. It specifically recognizes and cuts polyglutamylated microtubules with short polyglutamate tails to promote reorganization of cellular microtubule arrays and the release of microtubules from the CENTROSOME following nucleation. It is critical for the biogenesis and maintenance of complex microtubule arrays in AXONS; SPINDLE APPARATUS; and CILIA. Mutations in the spastin gene (SPAST) are associated with type 4 of HEREDITARY SPASTIC PARAPLEGIA.
