Disease

ATLA1_HUMAN Hereditary sensory and autonomic neuropathy type 1;Autosomal dominant spastic paraplegia type 3. Spastic paraplegia autosomal dominant 3 (SPG3) [MIM:182600: 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.

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.

Function

ATLA1_HUMAN GTPase tethering membranes through formation of trans-homooligomer and mediating homotypic fusion of endoplasmic reticulum membranes. Functions in endoplasmic reticulum tubular network biogenesis. May also regulate Golgi biogenesis. May regulate axonal development.[12] [13] [14] [15]

Publication Abstract from PubMed

The large GTPase atlastin belongs to the dynamin superfamily that has been widely implicated in facilitating membrane tubulation, fission, and in select cases, fusion. Mutations spread across atlastin isoform 1 (atlastin-1) have been identified in patients suffering from hereditary spastic paraplegia (HSP), a neurodegenerative disorder affecting motor neuron function in the lower extremities. On a molecular level, atlastin-1 associates with high membrane curvature and fusion events at the endoplasmic reticulum and cis-Golgi. Here we report crystal structures of atlastin-1 comprising the G and middle domains in two different conformations. Although the orientation of the middle domain relative to the G domain is different in the two structures, both reveal dimeric assemblies with a common, GDP-bound G domain dimer. In contrast, dimer formation in solution is observed only in the presence of GTP and transition state analogs, similar to other G proteins that are activated by nucleotide-dependent dimerization. Analyses of solution scattering data suggest that upon nucleotide binding, the protein adopts a somewhat extended, dimeric conformation that is reminiscent of one of the two crystal structures. These structural studies suggest a model for nucleotide-dependent regulation of atlastin with implications for membrane fusion. This mechanism is affected in several mutants associated with HSP, providing insights into disease pathogenesis.
