The amyotrophic lateral sclerosis 2 (ALS2) C-terminal like (ALS2CL) gene is an ALS2 homologous gene, located on human chromosome 3p21.31. It encodes a homo-dimeric protein that forms an ALS2-ALS2CL heteromeric complex with ALS2 oligomer. This complex co-localizes in the membrane compartments.
Specificity
Anti-ALS2CL (N-terminal) specifically recognizes human ALS2CL.
Application
Anti-ALS2CL (N-terminal) antibody produced in rabbit is suitable for immunoblotting.
Biochem/physiol Actions
The expression of amyotrophic lateral sclerosis 2 (ALS2) C-terminal like (ALS2CL) along with Ras-related protein Rab-5A (Rab5) causes the distinctive tubulation phenotype of endosome compartments. It also results in the co-localization of ALS2CL and Rab5. This protein possesses a weak Rab5-guanine nucleotide exchange factor (GEF) activity, but strongly binds to Rab5. Also, the ALS2CL protein suppresses the endosome enlargement induced by ALS2. In contrast to ALS2, ALS2CL might be considered as a critical moiety in modulating the ALS2 and Rab5 mediated endosome dynamics in the cell. The N-terminal region of the ALS2CL protein specifically regulates the endosome-autophagosome mediated endolysosomal trafficking. It controls the growth of neurites.
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, the causative gene product for a number of recessive motor neuron diseases, is a guanine-nucleotide exchange factor for Rab5, and acts as a modulator for endosome dynamics. Recently, we have identified a novel ALS2 homolog, ALS2CL, which is highly
After ischemic stroke, cell damage propagates from infarct core to surrounding tissues (penumbra). To reveal proteins involved in neurodegeneration and neuroprotection in penumbra, we studied protein expression changes in 2-mm ring around the core of photothrombotic infarct induced in the

Objective- The topographical distribution of atherosclerosis in vasculature underscores the importance of shear stress in regulating endothelium. With a systems approach integrating sequencing data, the current study aims to explore the link between shear stress-regulated master transcription factor and its
ALS2, the causative gene product for juvenile recessive amyotrophic lateral sclerosis (ALS2), is a guanine-nucleotide exchange factor for the small GTPase Rab5. Here, we report a novel ALS2 homologous gene, ALS2 C-terminal like (ALS2CL), which encodes a 108-kD ALS2CL protein.
