Target Information

HLA-DR, like other MHC class II molecules, is a transmembrane glycoprotein composed of a 36 kDa alpha chain (DRA) and a 27 kDa beta chain (DRB). The alpha chain gene contains 5 exons: exon 1 encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, and exon 4 encodes the transmembrane domain and cytoplasmic tail. DRA does not have polymorphisms in the peptide-binding region and acts as the sole alpha chain for DRB1, DRB3, DRB4, and DRB5. The beta chain contains polymorphisms that determine peptide-binding specificities. HLA-DR is expressed primarily on antigen-presenting cells such as B lymphocytes, monocytes, macrophages, thymic epithelial cells, and activated T lymphocytes. The human MHC class II molecules (DR, DQ, DP) bind intracellularly processed peptides, present them to T-helper cells, and play a critical role in initiating immune responses.
