Armadillo repeat is the name of a characteristic repetitive amino acid sequence found in β-catenin and many other proteins like α-importin plakoglobin or adenomatous polyposis coli (APC). Its name derives from the historical name of the β-catenin gene in the fruitfly Drosophila: where they were first discovered. Armadillo repeats are approximately 40 amino acids long and proteins that contain them usually have many tandemly repeated copies.
