Figure 3. Substitution of glutamic acid with glutamine at position 35 significantly reduces the functional strength of KIR2DL2*001.

Figure 3

(A) Stable YT-Indy cell lines expressing KIR2DL2*001 or KIR2DL2*001 mutant with glutamic acid at the amino acid position 35 replaced with glutamine. YT-Indy transfected with empty vector was used as mock control. Similar expression of KIR2DL2/L3 in the cell lines was confirmed by flow cytometry. (B) 721.221 was stably transduced with MSCV vector containing HLA-Cw07 ligand. (C) Specific killing of YT-Indy expressing KIR2DL2*001 or KIR2DL2*001 mutants (2DL2 E35Q) were assessed against 721.221-Cw07 by BADTA release assay. The experiments were repeated at least 3 times. P value was calculated using Student T test. Error bars represent SD.
