WebbInvariant chain stabilizes ___. MHC II: Invariant chain helps traffic MHC II to the ___. endocytic vesicles: MHC II is trafficked to the endocytic vesicles by this protein: invariant chain ___ pathogens escape the phagocytic pathway. intracelllular: Both self and non-self-cytoplasmic proteins are targeted for destruction by ___. During synthesis of class II MHC in the endoplasmic reticulum, the α and β chains are produced and complexed with a special polypeptide known as the invariant chain. The nascent MHC class II protein in the rough ER has its peptide-binding cleft blocked by the invariant chain (Ii; a trimer) to prevent it from binding cellular peptides or peptides from the endogenous pathway (such as those that would be loaded onto class I MHC).
