CC -!- FUNCTION: Voltage-gated sodium channel (Nav) inhibitor. 1 uM completely
CC inhibits insect voltage-gated sodium channel inactivation (DmNav1 from
CC D.melanogaster). {ECO:0000269|PubMed:19609479}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}. Nematocyst {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the sea anemone short toxin (type III) family.
CC {ECO:0000305}.
CC -!- CAUTION: Opinions are divided on whether Anemonia viridis (Forsskal,
CC 1775) and Anemonia sulcata (Pennant, 1777) are separate species.
CC {ECO:0000305}.
