Abstract:mu-Conotoxin (muCTX) KIIIA is of special interest both functionally and structurally because (1) it blocks neuronal voltage-gated sodium (Na v ) channels involved in pain signalling (Zhang et al., 2007, J. Biol. Chem.) and (2) unlike previously discovered muCTXs (most >22 amino acids), KIIIA has only 16 amino acids, missing amino acids in the N-terminal section. We have performed preliminary molecular dynamics simulations of muCTX KIIIA docking to a model of the Na v 1.4 outer vestibule (Choudhary et al, 2007… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
