Example sentences for: riα
How can you use “riα” in a sentence? Here are some example sentences to help you improve your vocabulary:
A previous report using immunofluorescence demonstrated colocalization of RIα with the nicotinic acetylcholine receptor (nAChR) at the NMJ postsynaptic membrane [ 19 ] . We used immunohistochemistry coupled with confocal microscopy to acquire detailed information as to the intracellular localization of D-AKAP1 in the several regions of the NMJ and adjacent intercostal muscle to compare with that of RIα.
We found that RIα occupies the same region as mitochondria in intercostal muscle.
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.
in lipid metabolism [ 39 40 ] , and a possible function of USF in tuning RIα/RIIβ ratio by activating RIα transcription and inhibiting RIIβ transcription is an interesting target of further investigation.
This observation is supported by previous work that demonstrated RIα codistribution with nAChR [ 19 ] and D-AKAP1 [ 17 ] suggesting that this AKAP is the anchoring protein recruiting RIα to this membrane.
