APPLICATION OF CALCICLUDINE
Calcicludine (CAC) is a 60-amino acid polypeptide from the venom of Dendroaspis angusticeps. Calcicludine, a venom peptide of the Kunitz-type protease inhibitor family, is a potent blocker of high-threshold Ca2+ channels with a high affinity for L-type channels in cerebellar granule neurons.
