CC   -!- FUNCTION: Antimicrobial peptide. Has low activity against the Gram-
CC       positive bacterium S.aureus (MIC=12.5 uM) and the Gram-negative
CC       bacterium E.coli (MIC=25 uM). Has weak hemolytic activity against human
CC       erythrocytes. {ECO:0000269|PubMed:19539775}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:19539775}.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin glands.
CC       {ECO:0000269|PubMed:19539775}.
CC   -!- SIMILARITY: Belongs to the frog skin active peptide (FSAP) family.
CC       Brevinin subfamily. {ECO:0000255}.
