Coiled-coil N-terminus of APC, dimerization domain
APC_N_CC is the N-terminal, coiled-coil dimerization domain of the adenomatosis polyposis coli (APC) tumor-repressor proteins. It plays a key role in the regulation of cellular levels of the oncogene product beta-catenin. Coiled-coil regions are binding repeats that in this case bind to the armadillo repeat region of beta-catenin.
