[[https://www.uniprot.org/uniprot/SCX1_TITSE SCX1_TITSE]] Beta toxins bind voltage-independently at site-4 of sodium channels (Nav) and shift the voltage of activation toward more negative potentials thereby affecting sodium channel activation and promoting spontaneous and repetitive firing. In addition, it stimulates the release of NO, IL-6 and TNF-alpha in J774.1 cells (PubMed:21549737). This toxin is active against both mammals and insects.<ref>PMID:21549737</ref>
