CC   -!- FUNCTION: Thanks to its amphiphilic alpha-helice(s), it may integrate
CC       into membrane phospholipids, leading to lysis of the membrane. Has no
CC       substantial hemolytic activity. Has antibacterial activity with a broad
CC       spectrum against various species of bacteria including both Gram-
CC       positive and Gram-negative groups.
CC   -!- SUBUNIT: Exists as aggregates of 3-4 molecules. {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin glands.
CC   -!- SIMILARITY: Belongs to the grammistin family. Group 3 subfamily.
CC       {ECO:0000305}.
