[[https://www.uniprot.org/uniprot/ERAP1_HUMAN ERAP1_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. Strongly prefers substrates 9-16 residues long. Rapidly degrades 13-mer to a 9-mer and then stops. Preferentially hydrolyzes the residue Leu and peptides with a hydrophobic C-terminus, while it has weak activity toward peptides with charged C-terminus. May play a role in the inactivation of peptide hormones. May be involved in the regulation of blood pressure through the inactivation of angiotensin II and/or the generation of bradykinin in the kidney.<ref>PMID:15908954</ref> <ref>PMID:16286653</ref> <ref>PMID:21478864</ref>

== Publication Abstract from PubMed ==
 +
Endoplasmic reticulum aminopeptidase 1 (ERAP1) is an essential component of the immune system, because it trims peptide precursors and generates the N--restricted epitopes. To examine ERAP1's unique properties of length- and sequence-dependent processing of antigen precursors, we report a 2.3 A resolution complex structure of the ERAP1 regulatory domain. Our study reveals a binding conformation of ERAP1 to the carboxyl terminus of a peptide, and thus provides direct evidence for the molecular ruler mechanism.
