Conotoxin MVIIC omega
Hintergrund
Omega-conotoxin MVIIC has been isolated from the venom of the cone Conus magus. omega-conotoxin MVIIC inhibits presynaptic Ca2+ channels, including the Ca2+ channels responsible for Ca2+ uptake by rat brain synaptosomes, the P-type Ca2+ channels in cerebellar Purkinje cells, and a significant fraction of omega-conotoxin GVIA-resistant currents in hippocampal CA1 neurons. omega-conotoxin MVIIC also presents an inhibition of omega-conotoxin GVIA-resistant depolarization-induced neurotransmitter release in cerebellar neurons of rats.
