Protein

Sarafotoxin-D

Gene
N/A
Organism
Atractaspis engaddensis (Israeli burrowing asp) (Israeli mole viper)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Vasoconstrictor activity. These toxins cause cardiac arrest probably as a result of coronary vasospasm. May act by displaying agonistic activities towards endothelin-1 and -2 receptors (EDNRA and EDNRB).1 Publication
