== Function ==
[https://www.uniprot.org/uniprot/ERAP2_HUMAN ERAP2_HUMAN] Aminopeptidase that plays a central role in peptide trimming, a step required for the generation of most HLA class I-binding peptides. Peptide trimming is essential to customize longer precursor peptides to fit them to the correct length required for presentation on MHC class I molecules. Preferentially hydrolyzes the basic residues Arg and Lys.<ref>PMID:12799365</ref> <ref>PMID:15908954</ref> <ref>PMID:16286653</ref>
