Structural features of MHC class I molecules that might facilitate alternative pathways of presentation

Immunol Today. 2000 Feb;21(2):83-8. doi: 10.1016/s0167-5699(98)01426-1.

Abstract

Comparisons of the structures of different mouse MHC class I molecules define how polymorphic residues determine the unique structural motif and atomic anchoring of their bound peptides. Here, Ted Hansen and colleagues speculate that quantitative differences in how class I molecules interact with peptide, beta2-microglobulin and molecular chaperones that facilitate peptide loading might determine their relative participation in different pathways of antigen presentation.
