CC   -!- FUNCTION: Modifies current passing through the fast sodium channel
CC       (Nav) in neuroblastoma cells, leading to delayed and incomplete
CC       inactivation. Paralyzes the shore crab (C.maenas) by tetanic
CC       contractions after intramuscular injection.
CC       {ECO:0000269|PubMed:11072049}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}. Nematocyst {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the sea anemone sodium channel inhibitory toxin
CC       family. Type I subfamily. {ECO:0000305}.
