μ-Conotoxin BuIIIB, is a peptide toxin originally isolated from Conus Bullatus (Bubble cone). It is characterized by a six-cysteine frame-work (-CC-C-C-CC-) cross-linked by three disulfide bridges. μ-Conotoxin BuIIIB was demonstrated to be a potent irreversible inhibitor of the NaV skeletal muscle subtype NaV1.4 heterologously expressed in Xenopus oocytes. 1 μM toxin was shown to block 96% of the channel. In addition μ-conotoxin BuIIIB potently blocks NaV1.3 expressed in oocytes, with an IC50 of 0.1 μM. NaV1.3 is involved in pain perception; therefore μ-conotoxin BuIIIB should serve as a valuable tool to evaluate the contribution of the NaV1.3 subtype to various pain states.
