Major Histocompatibility Complex Class II DO Beta (HLA-DOB) is a part of the HLA class II beta chain paralogues. This class II beta chain is a heterodimer which is located in intracellular vesicles and consists of an alpha (DOA) and a beta chain (DOB), both anchored in the membrane. HLA-DOB which interacts with the HLA-DM molecule in B-cells is a significant modulator in the HLA class II restricted antigen presentation pathway. Class II molecules are expressed in antigen presenting cells such as B lymphocytes, dendritic cells and macrophages.
HLA-DOB Human Recombinant produced in E. coli is a single polypeptide chain containing 222 amino acids (27-224) and having a molecular mass of 25.2 kDa.HLA-DOB is fused to a 24 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
UniProt Protein Function: | HLA-DOB: 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: 6p21.32 Cellular Component: lysosomal membrane; lysosome; MHC class II protein complex Molecular Function:MHC class II receptor activity Biological Process: antigen processing and presentation of exogenous peptide antigen via MHC class II; negative regulation of antigen processing and presentation of peptide antigen via MHC class II |
NCBI Summary: | HLA-DOB belongs to the HLA class II beta chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DOA) and a beta chain (DOB), both anchored in the membrane. It is located in intracellular vesicles. DO suppresses peptide loading of MHC class II molecules by inhibiting HLA-DM. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). The beta chain is approximately 26-28 kDa and its gene contains 6 exons. Exon one encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, exon 4 encodes the transmembrane domain and exon 5 encodes the cytoplasmic tail.
