AMACO is a member of the von Willebrand factor A-like (VWA) domain containing protein superfamily and consists of three VWA-like domains, two EGF-like domains, a cysteine-rich domain and a unique C-terminal domain.^[6] AMACO is an extracellular matrix protein and mostly deposited adjacent to basement membranes.^[7]

AMACO binds directly to FRAS1 which is part of the Fraser complex important for epithelial-connective tissue interaction,^[8] the exact biological role of AMACO, however, is still unknown. In 2005 AMACO was found markedly induced in colon cancers;^[9] indicating that it might be a good candidate as a biomarker for this type of cancer.
