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.
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.
| UniProt Protein Function: | HLA-DOA: Important modulator in the HLA class II restricted antigen presentation pathway by interaction with the HLA-DM molecule in B-cells. Modifies peptide exchange activity of HLA-DM. Belongs to the MHC class II family. |
| UniProt Protein Details: | Protein type:Membrane protein, integral Chromosomal Location of Human Ortholog: 6p21.3 Cellular Component: endosome membrane; integral to membrane; lysosomal membrane; MHC class II protein complex; plasma membrane Molecular Function:MHC class II receptor activity; protein binding Biological Process: antigen processing and presentation of exogenous peptide antigen via MHC class II; immune response; negative regulation of antigen processing and presentation of peptide antigen via MHC class II; regulation of T cell differentiation; signal transduction |
| NCBI Summary: | HLA-DOA belongs to the HLA class II alpha chain paralogues. HLA-DOA forms a heterodimer with HLA-DOB. The heterodimer, HLA-DO, is found in lysosomes in B cells and regulates HLA-DM-mediated peptide loading on MHC class II molecules. In comparison with classical HLA class II molecules, this gene exhibits very little sequence variation, especially at the protein level. [provided by RefSeq, Jul 2008] |
