In order to accurately define domains required for peptide transporter function, a molecular approach based on the construction of a panel of human TAP1 mutants and their expression in TAP1(-/-) cells was employed. The characteristics and biological activity of the various TAP1 mutants were determined, and compared to that of wild-type TAP1 and TAP1(-/-) control cells. All mutant TAP1 proteins were localized in the ER and were capable of forming complexes with the TAP2 subunit. However, the TAP1 mutants analyzed transported peptides with different efficiencies and displayed a heterogeneous MHC class I surface expression pattern which was directly associated with their susceptibility to cytotoxic T lymphocyte-mediated lysis. Based on this study, the TAP1 mutants can be divided into three categories: those expressing a similar phenotype compared to TAP1(-/-) or wild-type TAP1 cells respectively, and those representing an intermediate phenotype in terms of peptide transport rate, MHC class I surface expression and immune recognition. Thus, the results provide evidence that specific regions in the TAP1 subunit are crucial for the proper processing and presentation of cytosolic antigens to MHC class I-restricted T cells, whereas others may play a minor role in this process."xsd:string |
