MHC Class 1 Protein
|
| |
Class I major histocompatibility complex proteins display short peptides, or antigens, derived from normal cell proteins. Peptide- loaded MHC proteins are located on the cell surface where they can be examined by passing T cells of the immune system. The MHC complex has two subunits. The smaller subunit, b2 microglobulin, resembles an... more »
