Rabbit Polyclonal VPS50 Antibody

The VPS50 antibody targets the VPS50 protein, a key component of the endosomal sorting complex required for transport (ESCRT)-related VARP/VPS52-53-54 complex. This complex plays a critical role in regulating endosome-to-trans-Golgi network retrograde transport, lysosomal function, and synaptic vesicle recycling. VPS50 (also known as VPS54 in some contexts) is particularly noted for its involvement in maintaining neuronal health and glucose metabolism. Studies link VPS50 dysfunction to neurodegenerative disorders, such as amyotrophic lateral sclerosis (ALS) in mouse models, and metabolic abnormalities like impaired insulin secretion. The antibody is widely used in research to study VPS50 expression, localization, and interaction partners via techniques like Western blotting, immunohistochemistry, and immunofluorescence. Its development has advanced understanding of intracellular trafficking mechanisms and their implications in disease pathways. Recent investigations also explore VPS50's role in autophagy and neuronal survival, highlighting its potential as a therapeutic target. Commercial VPS50 antibodies are typically validated in specific cell lines or tissues, with attention to cross-reactivity across species.
