FIGURE 4.

Expression of skeletal (Sk) or cardiac (Card) CyPet-CT1 in dysgenic mouse myotubes, either alone (A) or in combination with YPet-CaM (B). In the absence of YPet-CaM, both cardiac and skeletal CT1 were present only around the nucleus injected with cDNA (A). Upon co-expression with YPet-CaM, the skeletal CT1 was still restricted around the injected nucleusm whereas the cardiac CT1 was distributed throughout the cell, with only occasional accumulation around the injected nucleus (not shown). Bars, 10 μm.
