8.B.28.1.1
Mu-conotoxin (Mu-conopeptide) SIIIA of 73 aas.  Inhibits both Na⁺ and K⁺ channels specifically; thus K_v1.1 and K_v1.6 are inhibited, but other K⁺ channels tested were not (Leipold et al. 2016).  Of Na⁺ channels, this toxin moderately blocks rNav1.1/SCN1A, rNav1.2/SCN2A, rNav1.3/SCN3A, rNav1.4/SCN4A, and mNav1.6/SCN8A (Wang et al. 2006; Yao et al. 2008; Bulaj et al. 2005).
