Where are dipeptides located in HLA-A * 02 : 01?

Study presents X-ray crystal structures of the peptide-free state of HLA-A*02:01, together with structures that have dipeptides bound in the A and F pockets. Amino acid side chains lining the binding pockets switch in a coordinated fashion between a peptide-free unlocked state and a peptide-bound locked state.

What is the role of HLA-A Class 1 polymorphism?

Data suggest that the immunoproteasome is involved in pathologic MHC class I (HLA-A, B, C, F and G) expression and maintenance of myokine production in Idiopathic inflammatory myopathies (IIMs). The host HLA class I polymorphism might play an important role with the occurrence of Severe fever with thrombocytopenia syndrome (SFTS).

HLA-A*24:02 is associated with metronidazole-induced cutaneous adverse drug reactions in Han Chinese individuals: A pilot case-control study with both HLA gene and T cell receptor repertoire analysis. Two unique HLA-A*0201 restricted peptides derived from cyclin E as immunotherapeutic targets in leukemia.
