This domain contains armadillo-like repeats [1]. Proteins containing this domain interact with numerous other proteins, through these interactions they are involved in a wide variety of processes including carcinogenesis [2], control of cellular ageing and survival [1], regulation of circadian rhythm [3] and lysosomal sorting of G protein-coupled receptors [4].
