Epitope KAFSPEVIPMF   Epitope Alignment
KgFSPEVIPMF   diminished HLA binding or increased off-rate; diminished response; escape documented in this paper; replicative capacity reduced
Epitope Name KF11
Species (MHC/HLA human(B*57:01, B*57:03)

Variant Details

Showing 1 of 4 variants.

Variant ID.  3734
Variant Seq.  KgFSPEVIPMF
Mutations A/G
Epitope Location A2G
HXB2 Location A163G
Mutation Type DHB: diminished HLA binding or increased off-rate
DR: diminished response
E: escape documented in this paper
RCR: replicative capacity reduced
Epitope Subtype B
Variant Subtype B
Method Other
Note KgFSPEVIPMF, position-2 escape from KF11, results in a loss but not abrogation of HLA binding. The resulting VRC reduction is substantially reversed by compensatory S165N. Combination of A163G/S165N results in complete loss of epitope recognition by CTL.
