Allele-specific B pocket transplant in class I major histocompatibility complex protein changes requirement for anchor residue at P2 of peptide. (ox.ac.uk)
To investigate the role of an anchoring pocket in allele-specific peptide presentation by a major histocompatibility complex class I molecule, we "transplanted" a B pocket from HLA-A*0201 into HLA-B*2705 by site-directed mutagenesis. (ox.ac.uk)
B27.A2B also fails to present an HLA-B27-restricted influenza virus peptide [nucleoprotein (383-391)] to cytotoxic T lymphocytes (CTLs). (ox.ac.uk)
However, substitution of leucine, the predominant P2 anchor residue in A*0201-restricted peptides, for arginine, the P2 anchor in nucleoprotein-(383-391) and other B*2705-restricted peptides, restores recognition of B27.A2B by the same B*2705-restricted peptide-specific CTLs. (ox.ac.uk)
