The structure reveals both a highly charged basic surface that may interact with glycosaminoglycans in the brain and an abutting hydrophobic surface that is proposed to play an important functional role such as in dimerisation or ligand-binding. Structural similarities with cysteine-rich growth factors, taken together with its known growth-promoting properties, suggest the APP N-terminal domain could function as a growth factor in vivo [1].
