Webb14 juni 2024 · In MHC-I structures, a heavy chain (HC) comprising the two membrane-distal domains (I-α1 and I-α2), a membrane-proximal IgSF domain (I-α3), and a connecting peptide/transmembrane/cytoplasmic tail (CP/TM/CY) region, binds a free single IgSF domain molecule, β 2 -microglobulin (β 2 -m). 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.
