Variant Details

Showing 1 of 4 variants.

Variant ID.  1883
Epitope Seq.  SLYNTVATL
Variant Seq.  SLfNTVAvL
Mutations Y/F T/V
Epitope Location Y3F T8V
HXB2 Location Y79F T84V
Mutation Type E: escape documented in this paper
P: processing
SF: susceptible form
Method Chromium-release assay
Note This variant escaped from killing by Gag-epitope-specific CTL clonal lines when presented as an endogenously expressed sequence on transformed cells, but was recognized when exogenously loaded as synthetic peptide. A processing or epitope presentation mutation is assumed.
