WebUnlike antibodies, which can bind to antigens directly, T cell receptors can only recognize antigens that are bound to certain receptor molecules, called Major Histocompatibility … MHC class I molecules are heterodimers that consist of two polypeptide chains, α and β2-microglobulin (B2M). The two chains are linked noncovalently via interaction of B2M and the α3 domain. Only the α chain is polymorphic and encoded by a HLA gene, while the B2M subunit is not polymorphic and encoded by the Beta-2 microglobulin gene. The α3 domain is plasma membrane-spanning and interacts with the CD8 co-receptor of T-cells. The α3-CD8 interaction h…
