How can you use “akap” in a sentence? Here are some example sentences to help you improve your vocabulary:
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 also investigated the distribution of gravin at the NMJ because this AKAP is an autoantigen for myasthenia gravis, a degenerative disease of the NMJ.
Of the 7 kinase and AKAP labeling patterns shown in this paper, RIIα is the only one that strongly associates with the z-line (contrast with the phalloidin labeling shown in fig.
At least one AKAP, AKAP 450 is a large coiled-coil protein attaching PKA to the centrosome [ 19 ] .
Consistent with the observed mitochondrial staining by anti-D-AKAP1, it was shown previously that one of the two alternative NH2-terminal motifs of this AKAP is necessary and sufficient for targeting to mitochondria [ 28 ] . Interestingly, another AKAP governs voltage-dependent potentiation of L-type calcium channels through anchoring of PKA in transverse tubules [ 36 ] . Because this potentiation is not dependent on RIIα, it is thought that RIα is capable of this AKAP-directed modulation of calcium channel activity [ 37 ] .
