The alpha chain of [https://www.youtube.com/watch?v=2ZakngfbHSo Major Histocompatibility Complex (MHC)] protein has a groove that binds a wide range of peptides, and a small loop that binds CD8. Our example is [[2vaa]] (mouse H-2Kb).

[[2vaa]] contains three chains. Here, ConSurf colors are applied only to the alpha chain (chain A), while the beta chain (chain B) and the peptide (chain P) are shown as gray backbone traces.

'''ConSurfDB''' has a result with an APD of 1.63. The sides of the groove are variable, as expected (enabling it to bind a wide range of peptide sequences). The only groove residue that is conserved at greater than level 6 is Leu5 (level 8), part of a hydrophobic pocket that binds a peptide "anchor residue". Only a handful of surface residues are highly conserved (level 8), including Trp274 involved in binding CD8.
