Handout IG2-2 Class I MHC-Peptide Interactions Place the steps of the antigen-processing pathway for endogenous antigen in the correct order Alpha chain of class I MHC binds peptide. Endogenous antigen within cytosol is degraded by proteasome. Peptides are transported into endoplasmic reticulum by TAP Alpha chain of class I MHC binds β2-microglobulin. Peptide-class I MHC is transported to Golgj complex and then to cell surface. Class I MHC peptide binds to CD8+T cell.
