Background: Aminopeptidase PILS/ARTS1

ARTS1 encodes a zinc-dependent metalloprotease (1) known as aminopeptidase PILS (Puromycin-Insensitive Leucyl-Specific), ALAP (adipocyte-derived leucine aminopeptidase), TNFR (type 1 tumor necrosis factor receptor) shedding aminopeptidase regulator, or ERAP1 (endoplasmic reticulum aminopeptidase 1). ARTS1 is widely expressed and known to be present in the endoplasmic reticulum. The protein has four domains with a large cavity between domain II and IV that can accommodate large peptide substrates; the second domain contains the active site and the first domain caps the active site and provides binding sites for the amino terminus of the substrate peptides (2). The enzyme has a unique substrate preference amongst the M1-family of aminopeptidases for longer peptides of up to 16 residues (3, 4) that is consistent with its ability to trim antigen precursors for MHC class 1 presentation (5). Variants and polymorphisms identified in ARTS-1 have linked it to autoimmune disease (6), cancer (7), and hypertension (8). ARTS-1 has been shown to be secreted (9, 10) and cause activation of inflammasome and cathepsin B pathways (11) and consequently to have a direct role in innate immunity and contribute to autoinflammatory and autoimmune diseases (12). ARTS-1 is consequently a potential therapeutic target (12-14).
