LtXVIA (P02623) Protein Card

General Information
Name LtXVIA
Alternative name(s) Lt16.1,Lt16a
Organism Conus litteratus
Organism region Indo-Pacific
Organism diet vermivorous
Protein Type Wild type
Protein precursor LtXVIA precursor (1170)
Notes This sequence was directly derived from the precursor: some post-translational modifications may be missing. The final Arg residue is probably cleaved off but Zhou et al. (2015) studied the activity of this peptide (with the C-terminal Arg residue). Remarkably, this peptide inhibits both TTX-sensitive and TTX-resistant sodium currents in rat DRG.
