Entrez Gene Summary for HLA-DRB3 Gene

  • HLA-DRB3 belongs to the HLA class II beta chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DRA) and a beta (DRB) chain, both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells. 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. Within the DR molecule the beta chain contains all the polymorphisms specifying the peptide binding specificities. Typing for these polymorphisms is routinely done for bone marrow and kidney transplantation. There are multiple pseudogenes of this gene. [provided by RefSeq, Feb 2020]

UniProtKB/Swiss-Prot Summary for HLA-DRB3 Gene

  • A beta chain of antigen-presenting major histocompatibility complex class II (MHCII) molecule. In complex with the alpha chain HLA-DRA, displays antigenic peptides on professional antigen presenting cells (APCs) for recognition by alpha-beta T cell receptor (TCR) on HLA-DRB3-restricted CD4-positive T cells. This guides antigen-specific T-helper effector functions, both antibody-mediated immune response and macrophage activation, to ultimately eliminate the infectious agents and transformed cells. Typically presents extracellular peptide antigens of 10 to 30 amino acids that arise from proteolysis of endocytosed antigens in lysosomes (PubMed:2788702, PubMed:2463305, PubMed:16148104, PubMed:19531622, PubMed:20368442, PubMed:19830726, PubMed:23569328, PubMed:22929521, PubMed:30282837, PubMed:31020640, PubMed:31333679, PubMed:31308093). In the tumor microenvironment, presents antigenic peptides that are primarily generated in tumor-resident APCs likely via phagocytosis of apoptotic tumor cells or macropinocytosis of secreted tumor proteins (By similarity). Presents peptides derived from intracellular proteins that are trapped in autolysosomes after macroautophagy, a mechanism especially relevant for T cell selection in the thymus and central immune tolerance (By similarity). The selection of the immunodominant epitopes follows two processing modes: 'bind first, cut/trim later' for pathogen-derived antigenic peptides and 'cut first, bind later' for autoantigens/self-peptides. The anchor residue at position 1 of the peptide N-terminus, usually a large hydrophobic residue, is essential for high affinity interaction with MHCII molecules (By similarity).

Upon EBV infection, presents to CD4-positive T cells latent antigen EBNA2 (PRSPTVFYNIPPMPLPPSQL) and lytic antigen BZLF1 (LTAYHVSTAPTGSWF) peptides, driving oligoclonal expansion and selection of virus-specific memory T cell subsets with cytotoxic potential to directly eliminate virus-infected B cells (PubMed:31308093, PubMed:23569328). Presents viral epitopes derived from HHV-6B U11, gB/U39 and gH/U48 antigens to polyfunctional CD4-positive T cells with cytotoxic activity implicated in control of HHV-6B infection (PubMed:31020640). Plays a minor role in CD4-positive T cell immune response against Dengue virus by presenting conserved peptides from capsid and non-structural NS3 proteins (PubMed:31333679). Displays peptides derived from IAV matrix protein M, implying a role in protection against IAV infection (PubMed:19830726). In the context of tumor immunesurveillance, may present to T-helper 1 cells an immunogenic epitope derived from tumor-associated antigen WT1 (KRYFKLSHLQMHSRKH), likely providing for effective antitumor immunity in a wide range of solid and hematological malignancies (PubMed:22929521). Presents to Vbeta2-positive T-helper 1 cells specifically an immunodominant peptide derived from tumor antigen CTAG1A/NY-ESO-1(PGVLLKEFTVSGNILTIRLTAADHR) and confers protective memory response (PubMed:19531622, PubMed:20368442). In metastatic epithelial tumors, presents to intratumoral CD4-positive T cells a TP53 neoantigen (HYNYMCNSSCMGSMNRRPILTIITL) carrying G245S hotspot driver mutation and may mediate tumor regression (PubMed:30282837).

    29962 Da
    Quaternary structure:
    • Heterotrimer that consists of an alpha chain HLA-DRA, a beta chain HLA-DRB1 and a peptide (peptide-MHCII) (PubMed:17583734, PubMed:18697946). Newly synthesized alpha and beta chains forms a heterodimer (MHCII) that associates with the CD74/invariant chain (Ii) in the endoplasmic reticulum (ER). Ii is a trimer composed of three subunits and each subunit interacts with one MHCII dimer, blocking the peptide-binding cleft. As a result, MHCII molecules can not bind peptides present in the ER (By similarity). The complex of MHCII and CD74/Ii is transported in vesicles from ER to Golgi to lysosomes, where it encounters antigenic peptides generated via proteolysis of endocytosed antigens. MHCII dimers are dissociated from CD74/Ii by the combined action of proteolysis and HLA-DM (By similarity). Lysosomal enzymes such as cathepsin, degrade CD74/Ii leaving a 24 amino acid remnant called class II-associated Ii or CLIP. Interacts (via the peptide binding cleft) with CLIP; this interaction inhibits antigen peptide binding before entry in the endosomal compartment. The displacement of CLIP and replacement by a high affinity peptide in lysosomes is performed by HLA-DM heterodimer. HLA-DM catalyzes CLIP dissociation from MHCII, stabilizes empty MHCII and mediates the selection of high affinity peptides (By similarity). Interacts with HLA-DM heterodimer; this interaction is direct (By similarity). Interacts with TCR (via CDR3) (By similarity). Interacts (via beta-2 domain) with CD4 coreceptor (via Ig-like V-type domain); this interaction is of exceptionally low affinity yet necessary for optimal recognition of antigenic peptides (By similarity).

Variants for HLA-DRB3 Gene

Polymorphic Variants from UniProtKB/Swiss-Prot for HLA-DRB3 Gene

DRB3_HUMAN-P79483
Highly polymorphic. Polymorphic residues encode for the beta-1 domain of the peptide-binding cleft, where they contribute to variations in peptide binding and TCR recognition among different alleles. The sequence shown is that of DRB3*01:01. The sequences of common representative alleles of serologically distinct allele groups as defined in the catalog of common and well-documented HLA alleles, are described as variants of DRB3*01:01. The most frequent alleles in human population are DRB3*01:01 (DR52a), DRB3*02:02 (DR52b) and DRB3*03:01 (DR52c) (PubMed:23510415). Allele DRB3*01:01 belongs to an ancestral haplotype and is associated with autoimmune diseases that are linked to antigen presentation. It is found in more than 95% of the homozygous HPA-1B mothers that produce anti-HPA-1A antibodies, leading to neonatal alloimmune thrombocytopenia (NAIT) (PubMed:19494351, PubMed:19535639). In the context of hematological malignancy and T cell transplantation, alleles DRB3*01:01 and DRB3*02:02 present minor histocompatibility antigens derived respectively from host PTK2B and MR1 proteins, contributing to T cell-mediated graft-versus-leukemia effect and complete remission (PubMed:19706888). Allele DRB3*03:01 plays an important role in the outcome of HLA-identical sex-mismatched organ transplantation. Presents to T-helper cells a minor histocompatibility antigen encoded by the Y chromosome RPS4Y1 (VIKVNDTVQI), leading to the maturation of dendritic cells and expansion of antigen-specific cytotoxic T cells, ultimately triggering transplant rejection (PubMed:12944060).
