Fig. 5. Exchange of tail sequences in h1 CaP. Fusion of the tail sequences from either h2 CaP (h1-h2t) or ac. CaP(h1-act) alter the localization of the respective h1 CaP mutant construct in A7r5 cells and cause an increased association with peripheral actin structures, when compared with the wild-type molecule. Top row, actin visualized by Alexa 568 phalloidin; middle row, GFP fluorescence; bottom row, merged images.
