Structural basis of inhibition of human NaV1.8 by the tarantula venom peptide Protoxin-I
Bryan Neumann, Stephen McCarthy, Shane Gonen
This study determines the cryo-EM structures of human NaV1.8 with and without the peptide Protoxin-I, revealing how the peptide inhibits channel activation by displacing the VSDII S3-S4 linker.
