Other Information

**Key Characteristics:** ERAP1 is a metalloprotease enzyme that belongs to the aminopeptidase family. It is localized to the endoplasmic reticulum (ER) and is responsible for removing N-terminal peptides from newly synthesized Class I MHC molecules. This process is essential for the proper folding and assembly of MHC molecules, which are then transported to the cell surface for antigen presentation. ERAP1's activity is regulated by the presence of zinc ions, which are required for its catalytic function. **Pathways and Functions:** ERAP1's primary function is to process and present antigens to the immune system through the following pathways: 1. **Antigen Processing and Presentation via Class I MHC:** ERAP1 removes N-terminal peptides from newly synthesized Class I MHC molecules, allowing them to be presented to CD8+ T cells. 2. **Antigen Processing and Presentation via Class I MHC:** ERAP1 also processes and presents endogenous peptides via Class I MHC, ensuring the proper presentation of self-antigens. 3. **Angiogenesis Regulation:** ERAP1 has been shown to positively regulate angiogenesis, a process critical for tumor growth and metastasis. **Clinical Significance:** ERAP1's dysregulation has been implicated in various diseases, including: 1. **Autoimmune Disorders:** ERAP1's role in antigen presentation and immune response regulation makes it a potential target for the treatment of autoimmune diseases, such as multiple sclerosis and rheumatoid arthritis. 2. **Cancer:** ERAP1's involvement in angiogenesis and tumor growth suggests its potential as a therapeutic target for cancer treatment. 3. **Infectious Diseases:** ERAP1's role in antigen processing and presentation via Class I MHC makes it a potential target for the treatment of infectious diseases, such as HIV and tuberculosis. In conclusion, ERAP1 is a critical gene involved in the processing and presentation of antigens to the immune system. Its dysregulation has been implicated in various diseases, highlighting the need for further research into its role in human health and disease.
