CC   -!- FUNCTION: Sarcotoxins, which are potent bactericidal proteins, are
CC       produced in response to injury. They are cytotoxic to both Gram-
CC       positive and Gram-negative bacteria.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- SIMILARITY: Belongs to the cecropin family. {ECO:0000305}.
