FIGURE 4.
E1015K CaV2. 1 is delivered to somato-dendritic and presynaptic compartments. Hippocampal neurons (6 days in vitro) transfected with WT or E1015K α1A were fixed after 5 days and probed with antibodies against MAP-2 or synaptobrevin-2. Note the distribution of both EGFP-α1AWT EGFP-α1AE1015K in the soma and dendrites immunolabeled for MAP-2. In addition, co-localization with synaptobrevin is observed in punctate-like structures demonstrating localization of both WT and the E1015K α1A in the presynaptic terminals. Scale bars, 10 μm.
