Summary: Predicted to enable ATP hydrolysis activity; microtubule severing ATPase activity; and tubulin binding activity. Involved in anterograde axonal transport and axonal transport of mitochondrion. Acts upstream of or within microtubule severing. Located in microtubule cytoskeleton and nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; integumental system; and sensory organ. Used to study hereditary spastic paraplegia 4. Human ortholog(s) of this gene implicated in hereditary spastic paraplegia 4. Orthologous to human SPAST (spastin). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
