[[http://www.uniprot.org/uniprot/SRTX_ATREN SRTX_ATREN]] Vasoconstrictor activity. These toxins cause cardiac arrest probably as a result of coronary vasospasm.<ref>PMID:21889567</ref>  Sarafotoxin-B: vasoconstrictor activity. Causes cardiac arrest probably as a result of coronary vasospasm (By similarity). Displays high agonistic activities towards endothelin-2 receptor (EDNRB) (displays affinity in the picomolar range) and endothelin-1 receptor (EDNRA) (lower affinities) (PubMed:21889567).<ref>PMID:21889567</ref>
