Stichodactyla helianthus Neurotoxins
Overview
Stichodactyla helianthus neurotoxins (ShK) are 48-amino acid peptides produced by the Caribbean sea anemone for defense and prey capture. They potently block voltage-gated potassium channels and delay sodium channel inactivation. QYAOBIO supplies synthetic ShK and Dap22-modified analogs for ion channel pharmacology research.
Key Features
- Native ShK and Dap22-modified analog for altered channel selectivity
- Disulfide bridge folding confirmed by MS
- Active in crustacean and mammalian ion channel assays
