HLA-E - major histocompatibility complex, class I, E Gene
Also Known as QA1; HLA-6.2
Species: Homo sapiens
About HLA-E
This gene has 3 transcripts (splice variants), 1 gene allele, 572 orthologues and 22 paralogues. Ubiquitous expression in spleen (RPKM 452.2), lung (RPKM 398.4) and 24 other tissues.
Summary
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.
