QA1
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.

Forensic Context
A study in human post-mortem brain tissue demonstrated that the HLA-E was specifically up-regulated in chronic traumatic encephalopathy (CTE) compared to normal controls, as part of a cell adhesion molecules (CAMs) pathway alteration unique to CTE pathology [Cho et al. DOI:10.1038/s41598-020-65916-y].
