Specificity of MRAP bimolecular fluorescence complementation.
A, live CHO cells transfected with MRAP fused to YFP fragments on
opposite sides or the same side of the MRAP protein. B, live CHO
cells transfected with V5-MRAP-YFP-F2 and Gβ1-YFP-F1,
YFP-F1-V5-MRAP, and Gγ7-YFP-F2, or Gβ1-YFP-F1
and Gγ7-YFP-F2 as shown. Left panels, YFP
fluorescence. Right panels, surface expression of MRAP detected by
staining live cells with anti-V5 antibody.
