Background

HLA DOA, also known as HLA class II histocompatibility antigen DO alpha chain, is a 250 amino acid protein that is 28 kDa, found in lysosomes in B cells and controls HLA-DM-mediated peptide loading on MHC class II molecules. Current research is being done on several diseases and disorders including vogt-koyanagi-harada disease, alopecia universalis, alopecia, systemic lupus erythematosus, graft versus host disease, lupus erythematosus, rheumatoid arthritis, toxoplasmosis, autoimmune thyroiditis, leishmaniasis, myocarditis, diabetes mellitus, arthritis influenza, immunodeficiency, asthma, tuberculosis, thyroiditis, interferon, and hepatitis b. Interactions with the HLA DOA protein have shown to involve ENSG00000204252 and HLA-DMA proteins in immune response antigen presentation by MHC class II, G-protein signaling N-RAS regulation pathway, immune response IL-22 signaling pathway, immune response NFAT in immune response, immune response ICOS pathway in T-helper cell, phagosome, cell adhesion molecules (CAMs), antigen processing and presentation, intestinal immune network for IgA production,and type I diabetes mellitus pathway.
