Assembly and antigen-presenting function of MHC class I molecules in cells lacking the ER chaperone calreticulin.
MHC class I molecules expressed in a calreticulin-deficient cell line (K42) assembled with beta 2-microglobulin (beta2-m) normally, but their subsequent loading with optimal peptides was defective. Suboptimally loaded class I molecules were released into the secretory pathway. This occurred despite...
