HLA-DOA Recombinant Protein

Source : Escherichia Coli. HLA-DOA Human Recombinant produced in E. coli is a single polypeptide chain containing 215 amino acids (26-217) and having a molecular mass of 24.1kDa. HLA-DOA is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Major Histocompatibility Complex Class II DO Alpha (HLA-DOA) is a significant modulator in the HLA class II restricted antigen presentation pathway by interaction with the HLA-DM molecule in B-cells. HLA-DOA forms a heterodimer along with HLA-DOB. The heterodimer is located in lysosomes in B cells and regulates HLA-DM-mediated peptide loading on MHC class II molecules. HLA-DOA exhibits very little sequence variation, particularly at the protein level.
