Site-specific mutations, disrupting the N-linked glycosylations in GP, do not affect co-localization of GP with HLA-A*0201. Cells were stably transfected with either CFP-fused HLA-A*0201 (A,C) or CFP-fused NKp46 (B,D) and then transiently transfected with either YFP-fused wild type GP (A,B) or YFP-fused double mutant GP (C,D). Thirty hours post transfection, cells were assayed by confocal microscopy using a 40 × /1.3 UPLSAPO objective (magnification including ocular lens is 400 ×). Summary plot shows FRET efficiency in various samples. Results are representative images from 50 images taken from the experiment. Scale bar (20 μm) is shown at the bottom right corner of each plot. (E) Positive control, (F) Negative control, (G) Summary results. Graphs represent mean ± SEM. ***p < 0.001, ordinary one-way ANOVA multiple comparisons test.
