Autoimmune diseases afflict nearly 10% of the world's population and have a serious impact on survival and quality of life. Unfortunately, the specific pathogenesis of almost all autoimmune diseases is still unclear, with more research findings identifying some key pathogenic genes at the genetic level and several pathogenic inflammatory factor phenotypes. ERAP1 has been suggested as a potential therapeutic target for several autoimmune diseases, especially MHC-Ⅰ related. How the structure and antigenic peptide processing function of ERAP1 affect the pathogenesis of these autoimmune diseases needs to be elucidated more clearly. Genetic studies on single nucleotide polymorphism of ERAP1 provide a good bridge to better understand the relationship and pattern between ERAP1 structure, function, and disease. However, existing reviews have focused on the genetic association of ERAP1 SNPs with autoimmune diseases, and no one has specifically addressed how ERAP1 gene polymorphisms embodied at the protein level specifically mediate antigenic peptide editing and the development of multiple autoimmune diseases. In this paper, we present a comprehensive review of these ERAP1 SNPs associated with multiple autoimmune diseases, in particular the polymorphisms affecting their protein structure and enzyme function, and attempt to unravel the underlying structural and biochemical mechanisms by which ERAP1 affects the pathogenesis of multiple autoimmune diseases through the SNP-protein structure-function-disease relationship. This study will provide theoretical help and ideas for understanding the relationship between ERAP1 and autoimmune diseases and for drug design targeting wild-type and mutant proteins with different polymorphisms. |
