WebMHC class I molecules are heterodimers that consist of two polypeptide chains, α and β 2 -microglobulin (B2M). The two chains are linked noncovalently via interaction of B2M and the α 3 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.
