ID:ERAP2_HUMAN DESCRIPTION: RecName: Full=Endoplasmic reticulum aminopeptidase 2; EC=3.4.11.-; AltName: Full=Leukocyte-derived arginine aminopeptidase; Short=L-RAP; FUNCTION: 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. COFACTOR: Binds 1 zinc ion per subunit (By similarity). SUBUNIT: Heterodimer with ERAP1. SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Single-pass type II membrane protein. TISSUE SPECIFICITY: Ubiquitously expressed. Highly expressed in spleen and leukocytes. INDUCTION: By IFNG/IFN-gamma. PTM: N-glycosylated. MISCELLANEOUS: Defects in the expression of this gene may cause improper antigen processing, possibly leading to favor tumor escape from the immune surveillance. SIMILARITY: Belongs to the peptidase M1 family.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
