Aminopeptidase O (AP-O; also C9orf3) is a 93kD (predicted), intracellular member of the M1 metalloprotease family of enzymes. It is expressed in heart, testis and pancreas where it apparently cleaves N-terminal Arg and Asn residues. Human AP-O is 819 amino acids in length. It contains one catalytic domain (aa 167-589) with a Zn-binding site (His479-His483) and a C-terminal ARM region (aa 706-819). At least three additional isoforms exist. One shows a deletion of aa 455-553; a second has an 11 aa substitution for the C-terminal 265 amino acids; and a third shows both a deletion of aa 455-553 and an 11 aa substitution for the C-terminal 46 amino acids.
