FIG. 7.

Distributions and mobilities of CBX-RING1B BiFC complexes. (A) Fluorescence images of live HEK293T cells that transiently coexpressed the CBX proteins (indicated above the images) fused to VN173 and RING1B fused to YC173 (see Materials and Methods). The fluorescence represents CBX-RING1B complexes. (B) The fluorescence recovery in cells comparable to those shown in panel A was quantified and plotted as described for Fig. 1. The data represent mean values and standard deviations (error bars), and the images are representative of a majority of the cells in each population (see Table S1 in the supplemental material).
