CC   -!- FUNCTION: Has lytic and hemolytic activities. Its hemolytic activity is
CC       inhibited by phospholipids, but not by cholesterol. Has antibacterial
CC       activity with a broad spectrum against various species of bacteria
CC       including both Gram-positive and Gram-negative groups. Has ichthyotoxic
CC       activity. {ECO:0000269|Ref.2}.
CC   -!- SUBUNIT: Exists as aggregates of 3-4 molecules. {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin glands.
CC   -!- MASS SPECTROMETRY: Mass=1544; Method=MALDI;
CC       Evidence={ECO:0000269|Ref.1};
CC   -!- TOXIC DOSE: LD(50) is 4.0 ug/ml against killifish.
CC   -!- SIMILARITY: Belongs to the grammistin family. Group 2 subfamily.
CC       {ECO:0000305}.
