omega-Conotoxin MVIIC (trifluoroacetate salt)

omega-Conotoxin MVIIC is a peptide originally isolated from the marine mollusk C. magus. It blocks N-type calcium channels on rat superior cervical ganglions (SCGs) and P-type calcium channels on rat Purkinje neurons (Kds = 30 and ~50 nM, respectively, in the presence of 5 mM barium). It also blocks Q-type channels in rat CA3 neurons. omega-Conotoxin MVIIC binds to rat brain membranes (IC50 = 0.3 nM) and completely blocks calcium uptake by rat brain synaptosomes when used at a concentration of 2.5 µM in the presence of 5 mM potassium. It blocks potassium-evoked dopamine (Cay-21992) release from rat striatal slices (IC50 = ~128 nM) and potassium-evoked calcium-dependent glutamate release from rat brain synaptosomes.Formal Name: L-cysteinyl-L-lysylglycyl-L-lysylglycyl-L-alanyl-L-prolyl-L-cysteinyl-L-arginyl-L-lysyl-L-threonyl-L-methionyl-L-tyrosyl-L-alpha-aspartyl-L-cysteinyl-L-cysteinyl-L-serylglycyl-L-seryl-L-cysteinylglycyl-L-arginyl-L-arginylglycyl-L-lysyl-L-cysteinamide, cyclic (1->16),(8->20),(15->26)-tris(disulfide), 2,2,2-trifluoroacetate.
