CC   -!- FUNCTION: Inhibits voltage-gated potassium channels (Kv1/KCNA).
CC       {ECO:0000250|UniProtKB:P29186}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}. Nematocyst {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the sea anemone type 1 potassium channel toxin
CC       family. Type 1b subfamily.
CC   -!- CAUTION: Opinions are divided on whether Anemonia viridis (Forsskal,
CC       1775) and Anemonia sulcata (Pennant, 1777) are separate species.
CC       {ECO:0000305}.
