Détail du antigène

Antigène: HLA-E*01:03

Sujet: HLAE, sHLA-E, HLAE, MHC class I antigen E, MHC HLA-E alpha-1, MHC HLA-E alpha-2.1, MHC, QA1. HLA-E is a nonclassical member of the major histocompatibility complex class I gene locus. HLA-E protein shares a high level of homology with MHC Ia classical proteins: it has similar tertiary structure, associates with ≤2-microglobulin, and is able to present peptides to cytotoxic lymphocytes. The main function of HLA-E under normal conditions is to present peptides derived from the leader sequences of classical HLA class I proteins, thus serving for monitoring of expression of these molecules performed by cytotoxic lymphocytes.

Poids moléculaire: 258 kDa. Due to glycosylation, the protein migrates to 260-265 kDa under Non reducing (N) condition based on Tris-Bis PAGE result.
