[[https://www.uniprot.org/uniprot/NXL1_NAJKA NXL1_NAJKA]] The monomeric form binds with high affinity to muscular, Torpedo (muscle-type), and neuronal alpha-7 nicotinic acetylcholine receptors (nAChR). Has no effect on alpha-3/beta-2 nAChR. Causes paralysis by preventing acetylcholine binding to the nAChR. Does not show any blockade of the nicotine-evoked release of dopamine and does not affect ACh release. In mice lung cancer, causes reduction of tumor growth.<ref>PMID:18381281</ref> <ref>PMID:6771288</ref> <ref>PMID:6553056</ref> <ref>PMID:2086254</ref> <ref>PMID:9053737</ref> <ref>PMID:9305882</ref> <ref>PMID:9840221</ref> <ref>PMID:10574958</ref> <ref>PMID:18067132</ref> The homodimeric form binds with low affinity to Torpedo (muscle-type) and alpha-7 nAChRs, whereas it acquires the capacity to block alpha-3/beta-2 nAChRs.<ref>PMID:18381281</ref> <ref>PMID:6771288</ref> <ref>PMID:6553056</ref> <ref>PMID:2086254</ref> <ref>PMID:9053737</ref> <ref>PMID:9305882</ref> <ref>PMID:9840221</ref> <ref>PMID:10574958</ref> <ref>PMID:18067132</ref> |
