Interaction of the TNFR-Receptor Associated Factor TRAF1 with I-Kappa B Kinase-2 and TRAF2 Indicates a Regulatory Function for NF-Kappa B Signaling
Figure 2
TRAF2 competes with IKK2 for TRAF1 binding.
The indicated CFP-, YFP- or flag-tagged expression constructs were transfected into HEK-293 cells followed by FRET-microscopy to determine protein interactions. The signals in the CFP- and YFP-channel are shown, as well as a pseudo-colored calculated FRET images.
