Amyotrophic lateral sclerosis 2 (ALS2) protein also called as alsin, consists of three putative guanine exchange factor (GEF) domains, the RCC1-like domain (RLD), the Dbl and pleckstrin homology (DH/PH) domain, and a vacuolar protein sorting 9 (VPS9) domain. In addition, this protein also contains eight consecutive membrane occupation and recognition nexus (MORN) motifs. The ALS2 mRNA is ubiquitously expressed in the central nervous system (CNS) and non-neuronal tissues, with the highest expression in the cerebellum and kidney. The gene ALS2 is mapped to human chromosome 2q33.1.
Specificity
Anti-ALS2 specifically recognizes human ALS2.
Application
Anti-ALS2 antibody produced in rabbit is suitable for immunoblotting.
Biochem/physiol Actions
Loss-of-function mutations in the amyotrophic lateral sclerosis (ALS2) gene, accounts for several recessive motor neuron diseases, including forms of ALS , juvenile-onset PLS (PLSJ) and hereditary spastic paraplegia (HSP). ALS is a heterogeneous neurological disorder that affects large motor neurons of the central nervous system (CNS). ALS2 protein contains several domains, implicating roles in cell signaling and membrane dynamics. This protein has been shown to mediate the activation of Ras-related protein Rab-5A (Rab5) and Ras-related C3 botulinum toxin substrate 1 (Rac1)/ p21-activated kinase (PAK1). In the nervous system, the protein ALS2 is preferentially associated with the cytoplasmic side of the endosome membrane, it modulates endosome membrane trafficking and promotes neurite growth in neuronal cultures. ALS2 gene knockout mice exhibits neurological deficits, altered endosome trafficking, and degeneration of corticospinal neurons.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
Storage and Stability
For continuous use, store at 2–8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

ALS2/alsin is a member of guanine nucleotide exchange factors for the small GTPase Rab5 (Rab5GEFs), which act as modulators in endocytic pathway. Loss-of-function mutations in human ALS2 account for a number of juvenile recessive motor neuron diseases (MNDs). However, the
Autosomal recessive mutations in the ALS2 gene have been linked to juvenile-onset amyotrophic lateral sclerosis (ALS2), primary lateral sclerosis and juvenile-onset ascending hereditary spastic paraplegia. Except for two recently identified missense mutations, all other mutations in the ALS2 gene lead
Biallelic mutations of ALS2 cause a clinical spectrum of overlapping autosomal recessive neurodegenerative disorders: infantile-onset ascending hereditary spastic paralysis (IAHSP), juvenile primary lateral sclerosis (JPLS), and juvenile amyotrophic lateral sclerosis (ALS2). We report on eleven individuals affected with IAHSP from

Recessive ALS2 mutations are linked to three related but slightly different neurodegenerative disorders: amyotrophic lateral sclerosis, hereditary spastic paraplegia and primary lateral sclerosis. To investigate the function of the ALS2 encoded protein, we generated Als2 knock-out (KO) mice and zAls2
