Description
R-Type Ca2+ (Cav2.3) channel blocker -
Biological description
Peptide toxin that naturally occurs in the venom of the spider Hysterocrates gigas. Selectively blocks Cav2.3 (α1E, R-type) channels in a voltage dependent manner (IC50 = 15-30 nM). At higher concentrations, also blocks Cav2.1 channels in chromaffin cells.
