Accordingly the question arises as to how this approach can be compared with previous studies which demonstrate a visible colocalization of AChRs and α-DG in muscle cells stimulated by nerve terminals [ 19 ] or agrin [ 4 20 26 27 ] . First we note that the present results do support a significant colocalization of the two molecules in agrin stimulated cells as compared to controls (Figure 5), in general agreement with previous findings.
This putative association is strengthened by finding for the first time that targeting of RIα requires the AKAP binding surface [ 17 ] . Yotiao is another AKAP enriched at the NMJ, but appears to bind only RII [ 30 ] . PKA phosphorylates the nAChR when stimulated at the synapse by the neuropeptide CGRP and by adenosine from muscle responding to acetylcholine [reviewed by [ 31 ] ]. This phosphorylation may regulate the degradation of the nAChR [ 32 ] . Consistent with the action at the presynapse, it was shown that PKA facilitation of acetylcholine release is dependent on nerve endplate calcium concentration [ 33 ] . Based on our observation of colocalization with synaptophysin at presynaptic vesicles, RIα may be the isotype that influences this release of neurotransmitter.
We report here an analysis of the 3-D distances of immunogold-labeled tBid from contact sites on the periphery of liver mitochondria that strongly supports the colocalization of the two.
The high frequency correlation eliminates this contamination and avoids the somewhat arbitrary imposition of a threshold, while the above threshold correlation is intuitively a better measure of what we mean by "colocalization of aggregates" but of necessity depends upon the threshold chosen.
Figure 3) that there is less perfect colocalization of α-DG within AChR aggregates in the present study than reported previously (see for example [ 4 ] Figure 9 for a comparable study using Xenopus muscle cell cultures).
