CC   -!- FUNCTION: Antimicrobial peptide with activity against Gram-negative
CC       bacterium E.coli ATCC 25922 (MIC=25 uM), Gram-positive bacterium
CC       S.epidermidis ATCC 12228 (MIC=6.25 uM) and against fungus C.albicans
CC       ATCC 24433 (MIC=50 uM) (PubMed:29980138). Has an anti-inflammatory
CC       effect, since it inhibits the production of the pro-inflammatory
CC       cytokine TNF-alpha (PubMed:30734396). Has an activity of stimulation of
CC       insulin release, which may protect the species from being eaten by
CC       predators by causing fatal hypoglycemia (PubMed:30734396). Is cytotoxic
CC       to cancer line cells (PubMed:30734396). Shows moderate hemolysis on
CC       mouse erythrocytes (LC(50)=28 uM) (PubMed:30734396).
