Functional significance of tapasin membrane association and disulfide linkage to ERp57 in MHC class I presentation

Tapasin is disulfide linked to ERp57 within the peptide loading complex. In cell-free assays, a soluble variant of the tapasin-ERp57 dimer recruits MHC class I molecules and promotes peptide binding to them while soluble tapasin alone does not. Here we show that within cells, tapasin conjugation wit...
