| Annotation description: | Fig.4: Localization of beta2 to the postsynaptic specialization of cholinergic synapses in the superior cervical ganglion is assayed using a RA-labeled toxin (toxin F/neuronal bungarotoxin/nBgt) that specifically binds the alpha3/beta2 nAChR subtype. |

| Additional literature: | Describes toxin F/neuronal bungarotoxin/nBgt to be selective for alpha3/beta2 nAChRs; "NBT is a highly selective, slowly reversible, competitive antagonist of the α3β2 neuronal nAChR subunit combination. Changing either the α or β subunit results in a dramatic loss in NBT sensitivity (Duvoisinet al., 1989; Luetje et al., 1990)." @ PMID:9614216 Shows that fast postsynaptic cholinergic synaptic EPSPs in the superior cervical ganglion are mediated by nACHRs that contain the alpha3 subunits. @ PMID:16162937 |
