(Ii). A protein that binds to newly synthesized MHC class II molecules and promotes their egress from the endoplasmic reticulum. It blocks the peptide-binding site on nascent MHC class II molecules and targets Ii–MHC class II complexes to late endosomal and lysosomal antigen-processing compartment...
Major histocompatibility complex class I (MHC-I) molecules are cell surface proteins essential for antigen presentation1. MHC-I encoded by three gene loci (HLA-A, -B, and -C) are composed of a polymorphic heavy α-chain and an invariant β-2 microglobulin light chain9. The α1- and α2...

MHC class II (MHC-II) molecules function by binding peptides derived from either self or foreign proteins and expressing these peptides on the surface of antigen presenting cells (APCs) for recognition by CD4 T cells. MHC-II is known to exist on clusters on the surface of APCs, and a va...

MHC class I proteins are expressed on all nucleated cells and MHC class II are found on only a few specialized cell types; B‑cells, neutrophils, dendritic cells and thymic epithelial cells and can be induced on macrophages and human T cells. The MHC class III locus encodes for other ...
