Explanation:
Detailed explanation-1: -The MHC class II molecules, expressed by antigen presenting cells, are heterodimers composed of an alpha and a beta chain, which function to present processed antigen to helper T cells. The human MHC class II molecules, HLA-DR1 and HLA-DR3, crystallized not as monomers, but rather dimers of alpha beta heterodimers.
Detailed explanation-2: -Major histocompatibility complex (MHC) class I and class II proteins play a pivotal role in the adaptive branch of the immune system. Both classes of proteins share the task of presenting peptides on the cell surface for recognition by T cells.
