Structural highlights
Function
[CO13_CONST] Omega-conotoxins act at presynaptic membranes, they bind and block voltage-gated calcium channels (Cav). This peptide selectively targets N-type voltage-gated calcium channels (Cav2.2/CACNA1B). Displays an analgesic potency similar to MVIIA in a range of acute and chronic pain models in rodents, but has less adverse effects compared with identical dosages of MVIIA injected intrathecally.[1]
