  • Even though the striated labeling in the muscle fibers appears similar to the striations noted for D-AKAP1 and RIα and is where actin is prevalent, the overlap with the mitochondrial marker (cytochrome c) is poor, in contrast with observations of close overlap in cells [ 29 ] . In the NMJ, the D-AKAP2 pattern is rather diffuse, being present in both postsynaptic and presynaptic vicinities, and appears dissimilar to the mitochondrial pattern.

  • 7), it may be labeling the presynaptic membrane, consistent with reports of PKCβ localization to the presynaptic terminals of NMJs [ 22 23 ] . PKCβ initially associates with the cytoskeleton [ 50 ] . Phosphorylation at two places on the kinase core is required first to activate PKC, and second to release it from its cytoskeletal anchorage.

  • The observed bands may represent kinase anchored directly to the cytoskeleton, perhaps on the presynaptic side, where little gravin staining was found, or anchored to gravin, perhaps on the postsynaptic side.

  • Intense PKCβ immunoreactivity was found in both postsynaptic and presynaptic regions (fig.

  • PKC has been suggested to play a role in synapse stability and signal transduction at the NMJ [ 24 ] . When calcium influx through the nAChR occurs, acetylcholine appears to activate PKC phosphorylation of this receptor [reviewed by [ 31 ] ]. Phorbol ester activation of PKC causes loss of synapses and nAChR [ 49 ] . Because the presynaptic PKCβ fluorescence band parallels the nAChR band (see fig.
