Staining of normal human peripheral blood cells with 0.5 ug of mouse IgG1 kappa isotype control purified (open histogram) or 0.5 ug of HLA-E monoclonal antibody, clone 3D12HLA-E (Cat # MAB10879) (filled histogram) followed by Anti-mouse IgG biotin and streptavidin PE. Cells in the lymphocyte gate were used for analysis.
HLA-E belongs to the HLA class I heavy chain paralogues. This class I molecule is a heterodimer consisting of a heavy chain and a light chain (beta-2 microglobulin). The heavy chain is anchored in the membrane. HLA-E binds a restricted subset of peptides derived from the leader peptides of other class I molecules. The heavy chain is approximately 45 kDa and its gene contains 8 exons. Exon one encodes the leader peptide, exons 2 and 3 encode the alpha1 and alpha2 domains, which both bind the peptide, exon 4 encodes the alpha3 domain, exon 5 encodes the transmembrane region, and exons 6 and 7 encode the cytoplasmic tail.
