Conservation of important residues in the groove is obscured by inclusion in the MSA of proteins with different functions ([[#Example With Multiple Functions|see analysis above]]). The sides of the groove are variable due to many alleles that enable it to bind a wide range of peptide sequences. The only groove residue that is conserved at greater than level 7 is '''Tyr159''' (level 8), whose sidechain hydrogen bonds the main-chain oxygen of the amino-terminal peptide residue. Only a handful of surface residues are highly conserved (level 9), including '''Trp274''' involved in binding CD8. | Conservation of important residues in the groove is obscured by inclusion in the MSA of proteins with different functions ([[#Example With Multiple Functions|see analysis above]]).
