HLA-E

  • Official Full Name

    major histocompatibility complex, class I, E
  • Overview

    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.

    Protein Function

    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.
