Aminopeptidases hydrolyze N-terminal amino acids of proteins or peptide substrates. Major histocompatibility complex (MHC) class I molecules rely on aminopeptidases such as ERAP1 (MIM 606832) and LRAP to trim precursors to antigenic peptides in the endoplasmic reticulum (ER) following cleavage in the cytoplasm by tripeptidyl peptidase II (TPP2; MIM 190470) (Tanioka et al., 2003 [PubMed 12799365]).[supplied by OMIM, Mar 2008]
GeneCards Summary for ERAP2 Gene
ERAP2 (Endoplasmic Reticulum Aminopeptidase 2) is a Protein Coding gene. Diseases associated with ERAP2 include Birdshot Chorioretinopathy and Spondylitis. Among its related pathways are Antigen Presentation- Folding, assembly and peptide loading of class I MHC and Antigen processing- Ubiquitination and Proteasome degradation. GO annotations related to this gene include metallopeptidase activity and aminopeptidase activity. An important paralog of this gene is ENPEP.
UniProtKB/Swiss-Prot for ERAP2 Gene
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.
