Vasoconstrictor activity. These toxins cause cardiac arrest probably as a result of coronary vasospasm. The major effects of sarafotoxin-m are a progressive decrease in heart rate (bradycardia) that turns into an arrhythmic phase that is followed by an A-V block.1 Publication
Sarafotoxin-m: vasoconstrictor activity. Causes cardiac arrest probably as a result of coronary vasospasm (By similarity). Displays low agonistic activities towards endothelin-2 receptor (EDNRB) (displays affinity in the micromolar range) (PubMed:21889567).By similarity2 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
