Official Full Name HLA-DRB3 major histocompatibility complex, class II, DR beta 3 [ Homo sapiens ]
Background 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 (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. 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. DRB1 is expressed at a level five times higher than its paralogues DRB3, DRB4 and DRB5. The presence of DRB3 is linked with allelic variants of DRB1, otherwise it is omitted. There are 4 related pseudogenes: DRB2, DRB6, DRB7, DRB8 and DRB9.

    HLA-DRB3 has several biochemical functions, for example, MHC class II receptor activity, peptide antigen binding, protein binding. Some of the functions are cooperated with other proteins, some of the functions could acted by HLA-DRB3 itself. We selected most functions HLA-DRB3 had, and list some proteins which have the same functions with HLA-DRB3. You can find most of the proteins on our site.
