Neurotoxin
FUNCTION: Mu-conotoxins block voltage-gated sodium channels (Nav). This synthetic toxin moderately blocks rNav1.1/SCN1A, rNav1.2/SCN2A, rNav1.3/SCN3A, rNav1.4/SCN4A, rNav1.5/SCN5A, and mNav1.6/SCN8A (PubMed:21652775). This block is very slowly reversible (PubMed:16533055). Causes seizures when injected intracranially into mice. {ECO:0000269|PubMed:16533055, ECO:0000269|PubMed:21652775}.
