The ER protein tapasin (Tpn) forms a bridge between MHC class I H chain (HC)/beta(2)-microglobulin and the TAP peptide transporter. The function of this TAP-associated complex was unclear because it was reported that soluble Tpn that has lost TAP interaction would be fully competent in terms of peptide loading and Ag presentation. We found, however, that only wild-type human Tpn (hTpn), but not...
Intracellular antigens are continually presented to cytotoxic T lymphocytes by major histocompatibility complex (MHC) class I molecules, which consist of a polymorphic 43 kDa heavy chain and a 12 kDa soluble subunit beta 2-microglobulin (beta 2m), and which bind an 8-10 amino-acid antigenic peptide. The assembly of this trimolecular complex takes place in the lumen of the endoplasmic reticulum ...
Juvenile rheumatoid arthritis (JRA) comprises a group of chronic systemic inflammatory disorders that primarily affect joints and can cause long-term disability. JRA is likely to be a complex genetic trait, or a series of such traits, with both genetic and environmental factors contributing to the risk for developing the disease and to its progression. The HLA region on the short arm of chromos...
Effective CD8(+) T cell responses depend on presentation of a stable peptide repertoire by MHC class I (MHC I) molecules on the cell surface. The overall quality of peptide-MHC I complexes (pMHC I) is determined by poorly understood mechanisms that generate and load peptides with appropriate consensus motifs onto MHC I. In this article, we show that both tapasin (Tpn), a key component of the pe...
