Distribution of D-AKAP2 at the NMJ and adjacent muscle. D-AKAP2 labeling is diffuse in both pre-and postsynaptic regions of the NMJ. In muscle, D-AKAP2 labeling is in the actin region, but does not colocalize well with mitochondria. Indeed, the strongest labeling is perpendicular to the mitochondrial striations. scale bar = 10 μm.
