Official Full Name major histocompatibility complex, class I, E
Background 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.

    HLA-E has several biochemical functions, for example, MHC class I protein binding, beta-2-microglobulin binding, natural killer cell lectin-like receptor binding. Some of the functions are cooperated with other proteins, some of the functions could acted by HLA-E itself. We selected most functions HLA-E had, and list some proteins which have the same functions with HLA-E. You can find most of the proteins on our site.

    HLA-E has direct interactions with proteins and molecules. Those interactions were detected by several methods such as yeast two hybrid, co-IP, pull-down and so on. We selected proteins and molecules interacted with HLA-E here. Most of them are supplied by our site. Hope this information will be useful for your research of HLA-E.
