Variant Details

Showing 1 of 6 variants.

Variant ID.  1859
Epitope Seq.  SLYNTVATL
Variant Seq.  SLfNTiATL
Mutations Y/F V/I
Epitope Location Y3F V6I
HXB2 Location Y79F V82I
Mutation Type E: escape documented in this paper
NSF: non-susceptible form
SF: susceptible form
TCR: TCR related mutation
Method Chromium-release assay, Relative replication capacity assay, Sequence
Note CTL Clone 18030D23 recognizes this variant but Clone 161JxA14 from a different subject does not. Both clones recognize SL9 index sequence similarly. Since the clones are from different HIV-1 infected subjects, with different TCR sequences, TCR is seen to contribute to escape differentially in this instance.
