Target Information

HLA-DRA is one of the HLA class II alpha chain paralogues. This class II molecule is a heterodimer consisting of an alpha and a beta 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 alpha chain is approximately 33–35 kDa and its gene contains 5 exons.

• Exon 1 encodes the leader peptide
• Exons 2 and 3 encode the two extracellular domains
• Exon 4 encodes the transmembrane domain and cytoplasmic tail

DRA does not have polymorphisms in the peptide-binding part and acts as the sole alpha chain for DRB1, DRB3, DRB4, and DRB5.

HLA and MHC antibodies play a significant role in Immunopeptidomics, facilitating the identification and characterization of neoantigens through high-performance liquid chromatography coupled to tandem Mass Spectrometry.
