Atlastin-1 (D2E6) Rabbit Monoclonal Antibody #12728

Atlastin proteins are highly conserved members of the dynamin superfamily of membrane GTPases that are involved in the formation of vesicles for the endocytotic and secretory processes (1). Atlastins are required to establish and maintain the morphology of the tubular endoplasmic reticulum (ER) and are therefore important in ER function (2). GTP hydrolysis and dimerization are required for atlastin-dependent ER membrane fusion (3).
Atlastin GTPase 1 (ATL1) is primarily expressed in brain, while the related atlastin 2 and atlastin 3 proteins are ubiquitously expressed (4). Mutations in the atlastin 1 gene SPG3A and the ER defects that result are thought to cause one form of hereditary spastic paraplegia (HSP), a group of heterogeneous neurological disorders characterized by severe progressive spasticity of the lower limbs (5,6).
