The CHMP2B (Charged Multivesicular Body Protein 2B) antibody is a tool used to study the CHMP2B protein, a key component of the ESCRT-III (Endosomal Sorting Complex Required for Transport-III) complex. ESCRT-III mediates critical membrane remodeling processes, including cytokinesis, multivesicular body (MVB) formation, and viral budding. CHMP2B plays a role in membrane scission and cargo sorting, particularly in endosomal-lysosomal trafficking.
Mutations in the CHMP2B gene are linked to neurodegenerative disorders, notably frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS). These mutations, such as the pathogenic truncating variant (e.g., p.Thr104Asnfs*5), disrupt ESCRT-III function, leading to aberrant endosomal-lysosomal trafficking, accumulation of autophagosomes, and protein aggregates. CHMP2B-related FTD is characterized by neuronal inclusions positive for ubiquitin, p62. and TDP-43. though distinct from other FTD subtypes.
CHMP2B antibodies are essential in research to detect protein expression, localization, and aggregation in cellular and animal models. They are used in techniques like Western blotting, immunohistochemistry, and immunofluorescence to explore disease mechanisms, such as impaired autophagy and lysosomal dysfunction. Additionally, these antibodies aid in studying the interplay between CHMP2B mutations and other ALS/FTD-associated proteins (e.g., C9orf72. TDP-43). Understanding CHMP2B pathology contributes to developing therapeutic strategies targeting endosomal-lysosomal pathways in neurodegeneration.
