Researchers interested in studying possible interactions between lamellipodin (Lpd) and Mena performed the experiment below.  Lpd-FP4-2Mito is a fusino protein consisting of Lpd, the FP4 domain which has been shown to bind to Mena, and the 2Mito domain which has been shown to bind to the mitochondria.  The Lpd-Pro-Mito fusion protein is similar except that the FP4 domain has been replaced with a bunch of prolines that don’t really do anything other than act as a spacer.    Look at the immunofluorescence images and indicate which of the following was the most important result of this experiment.
