Major histocompatibility complex, class II, DP beta 1

HLA-DPB belongs to the HLA class II beta chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DPA) and a beta chain (DPB), 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 DP molecule both the alpha chain and the beta chain contain the polymorphisms specifying the peptide binding specificities, resulting in up to 4 different molecules.

Avoidance of an unrelated donor with a non-permissive T-cell-epitope mismatch at HLA-DPB1 might provide a practical clinical strategy for lowering the risks of mortality after unrelated-donor haemopoietic-cell transplantation.
Full-length HLA-DPB1 diversity in multiple alleles of individuals from Caucasian, Black, or Oriental origin.
Tilanus et al., Maastricht, Netherlands. In Tissue Antigens, 2012

Five amino acids in three HLA proteins explain most of the association between MHC and seropositive rheumatoid arthritis.
de Bakker et al., Boston, United States. In Nat Genet, 2012
Three amino acid positions (11, 71 and 74) in HLA-DRbeta1 and single-amino-acid polymorphisms in HLA-B (position 9) and HLA-DPbeta1 (position 9), all located in peptide-binding grooves, almost completely explain MHC association to rheumatoid arthritis risk.
