| - | + | [https://www.uniprot.org/uniprot/O16O3_CONST O16O3_CONST] Omega-conotoxins act at presynaptic membranes, they bind and block voltage-gated calcium channels (Cav). This peptide selectively targets Cav2.2/CACNA1B (IC(50)=160 nM) voltage-gated calcium channels (PubMed:26344359). When tested in mammals, this toxin displays an analgesic potency similar to MVIIA in a range of acute and chronic pain models in rodents, but has less adverse effects (tremor, diminution of spontaneous locomotor activity and bad coordinated locomotion) compared with identical dosages of MVIIA injected intrathecally.<ref>PMID:15880145</ref> <ref>PMID:26344359</ref> | |
