The COX11 antibody is a crucial tool in studying the cytochrome c oxidase (COX) complex, a key component of the mitochondrial electron transport chain. COX11. a nuclear-encoded protein, plays an essential role in the assembly of mitochondrial respiratory Complex IV (COX), specifically facilitating copper ion insertion into the catalytic subunit COX1. This process is vital for cellular energy production via oxidative phosphorylation. Dysregulation of COX11 or its associated pathways has been linked to mitochondrial disorders, neurodegenerative diseases, and cancer.
COX11 antibodies are widely used in research to investigate protein expression, localization, and interactions in mitochondrial studies. They enable techniques like Western blotting, immunohistochemistry, and immunofluorescence to assess COX11 levels in tissues or cultured cells, particularly in contexts of mitochondrial dysfunction. Additionally, these antibodies aid in exploring COX11's role in diseases such as Leigh syndrome, cardiomyopathy, and tumors, where altered mitochondrial metabolism is implicated.
Most commercially available COX11 antibodies are raised in rabbits or mice using specific peptide antigens, with validation across species like human, mouse, and rat. Researchers prioritize antibodies validated for specificity through knockout controls or siRNA silencing. Recent studies also utilize COX11 antibodies to probe its interactions with copper chaperones and redox-sensitive pathways, expanding understanding of mitochondrial metal homeostasis and stress responses.
