- | [[ | + | [[https://www.uniprot.org/uniprot/KURT_PARTR KURT_PARTR]] Alpha toxins bind voltage-independently at site-3 of sodium channels and inhibit the inactivation of the activated channels, thereby blocking neuronal transmission. This toxin acts on Nav1.2/SCN2A. Also binds to Cav3.1/CACNA1G and Cav3.2/CACNA1H T-type calcium channels with high affinity and inhibits the channels by modifying voltage-dependent gating. Another study (PubMed:11896142) shows that it also targets neuronal high-threshold calcium channels, including P-type, N-type, and L-type calcium channels (Cav), and others that still are unidentified pharmacologically.<ref>PMID:10196582</ref> <ref>PMID:11896142</ref> |
