背景信息

CHMP4A (Charged Multivesicular Body Protein 4A) is a key component of the Endosomal Sorting Complex Required for Transport (ESCRT)-III machinery, which plays essential roles in membrane remodeling processes such as cytokinesis, multivesicular body (MVB) formation, viral budding, and plasma membrane repair. As a member of the CHMP protein family, CHMP4A forms oligomeric filaments that mediate membrane scission by inducing negative curvature. It functions in coordination with other ESCRT complexes (ESCRT-0. -I, -II) to sort ubiquitinated cargo into intraluminal vesicles of MVBs for lysosomal degradation or extracellular release via exosomes.

Antibodies targeting CHMP4A are widely used to study its localization, expression, and interactions in cellular processes. They serve as critical tools for applications like Western blotting, immunofluorescence, and immunoprecipitation to investigate ESCRT-III dynamics in disease contexts. Dysregulation of CHMP4A has been implicated in cancer progression, neurodegenerative disorders (e.g., Alzheimer’s disease), and viral pathogenesis, as many enveloped viruses hijack the ESCRT pathway for budding. For example, CHMP4A overexpression has been observed in certain tumors, while mutations disrupting its function may impair abscission, leading to genomic instability. These antibodies also help explore CHMP4A’s non-canonical roles, such as regulating autophagy and apoptosis. Commercial CHMP4A antibodies are typically raised against specific epitopes (e.g., N-terminal or C-terminal regions) and validated for cross-reactivity across species (human, mouse, rat), though isoform specificity (vs. CHMP4B/C) requires careful verification due to high sequence homology.
