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.
