Background
This gene encodes a zinc metalloaminopeptidase of the M1 protease family that resides in the endoplasmic reticulum and functions in N-terminal trimming antigenic epitopes for presentation by major histocompatibility complex (MHC) class I molecules. Certain mutations in this gene are associated with the inflammatory arthritis syndrome ankylosing spondylitis and pre-eclampsia. This gene is located adjacent to a closely related aminopeptidase gene on chromosome 5. [provided by RefSeq, Jul 2016],
Function
cofactor:Binds 1 zinc ion per subunit.,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.,induction:By IFN-gamma.,miscellaneous:Defects in the expression of this gene may cause improper antigen processing, possibly leading to favor tumor escape from the immune surveillance.,PTM:N-glycosylated.,similarity:Belongs to the peptidase M1 family.,subunit:Heterodimer; with ERAP1.,tissue specificity:Ubiquitously expressed. Highly expressed in spleen and leukocytes.,
