RC   TISSUE=Kidney;
RG   The German cDNA consortium;
RL   Submitted (NOV-2004) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Aminopeptidase that plays a central role in peptide trimming,
CC       a step required for the generation of most HLA class I-binding
CC       peptides. Peptide trimming is essential to customize longer precursor
CC       peptides to fit them to the correct length required for presentation on
CC       MHC class I molecules. Preferentially hydrolyzes the basic residues Arg
CC       and Lys (By similarity). {ECO:0000250}.
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC   -!- SUBUNIT: Heterodimer with ERAP1. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC       Single-pass type II membrane protein {ECO:0000250}.
CC   -!- PTM: N-glycosylated. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the peptidase M1 family. {ECO:0000305}.
