ATG4A antibodies are essential tools for studying the role of ATG4A, a cysteine protease belonging to the autophagy-related (ATG) protein family. ATG4A, encoded by the ATG4A gene, is a key enzyme in the autophagy pathway, a conserved cellular degradation process critical for maintaining homeostasis. It specifically processes ATG8-family proteins (e.g., LC3) by cleaving their C-terminal residues to generate the lipid-conjugatable form (LC3-I), which is essential for autophagosome formation. ATG4A also delipidates lipidated LC3 (LC3-II) to recycle it from autophagosomal membranes, regulating autophagic flux. Dysregulation of ATG4A has been implicated in diseases such as cancer, neurodegenerative disorders, and infections, making it a potential therapeutic target.
ATG4A antibodies are widely used in techniques like Western blotting, immunofluorescence, and immunoprecipitation to detect protein expression, localization, and interactions. These antibodies help researchers investigate ATG4A's regulatory mechanisms, including post-translational modifications (e.g., phosphorylation) and its interplay with other autophagy-related proteins. Specific monoclonal or polyclonal antibodies targeting distinct epitopes are available, often raised in hosts like rabbits or mice. Validation via knockout cell lines or siRNA-mediated knockdown is crucial to ensure specificity, as ATG4A shares homology with other ATG4 family members (ATG4B, ATG4C, ATG4D). Research using these antibodies has advanced understanding of autophagy dynamics, disease-associated ATG4A dysfunction, and its potential as a biomarker or drug target.
