|Figure 6: Visualization of protein complexes composed of PPARα and (A) wild-type, (B) H383E,
(C) E387Q, (D) H390E, (E) L414R, and (F) R415A LXRα in living cells using Bimolecular
Fluorescence Complementation (BiFC) analysis. Fluorescence images of COS-7 cells expressing
ECFP-LXR, Venus-PPAR, and Cerulean-RXR proteins were acquired 24 hr after transfection
with indicated plasmids.
