  contains a C448Y substitution

• Mutation details: A CAG-promoter-driven loxP-flanked STOP cassette followed by a human full-length spastin (M1) containing a G to A point mutation at position 1343 in exon 11 within the AAA domain resulting in a cysteine to tyrosine change at amino acid 448 was inserted between exons 1 and 2 of the Gt(ROSA)26Sor locus. The C448Y mutation is located in the second pore loop of the AAA domain of spastin and destroys the microtubule-severing activity of the protein. This mutation is commonly found in patients with hereditary spastic paraplegia. (J:273408)
