Variant Details

Showing all: 1 variant(s).

Variant ID.  4202
Variant Seq.  kPQVPLRPMTY
Mutations R/K
Epitope Location R1K
HXB2 Location R71K
Mutation Type AHE: altered HLA expression
OV: observed variant
RCR: replicative capacity reduced
Method Other, Relative replication capacity assay
Note For mutation 71K, replication capacities, CD4 down-modulation capacities, and HLA-I down-modulation capacities expressed relative to that of the wild-type LANL consensus B Nef are 0.854, 1.002 and 0.972 respectively. Thus R71K has a very moderate effect on this epitope and only significantly on replication.
