Recently, endoplasmic reticulum aminopeptidase 1 (ERAP1) gene polymorphisms were associated with ankylosing spondylitis (AS) in genome-wide association studies (GWAS), associations which later were replicated across different populations, including the Romanian population. ERAP1 enzyme was proved to be involved in the fi nal trimming, to the optimal length, of the antigenic peptides before loading them to human leucocyte antigen (HLA) class I molecules, different variants of ERAP1 being able to modify the types of peptides presented by HLA I molecules (including HLA-B27) to the CD8+ T cells. This article presents a detailed description of the functions, structure and the pathogenic potential of ERAP1 in AS. [ABSTRACT FROM AUTHOR]
