HLA-DO is a dimeric Major Histocompatibility Complex (MHC) Class II protein composed of α- and β-subunits which interacts with HLA-DM in order to fine tune immunodominant epitope selection.[1][2] As elucidated by studies performed on its mouse-analog, H2-O, the polymorphic and evolutionarily conserved features of HLA-DO indicate that evolutionary benefits may be conferred to the host by this molecule.[3]
