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}.
