CC   -!- FUNCTION: The amidated Phylloseptin-1.2TR has weak antimicrobial
CC       activity against Gram-negative bacterium E.coli ATCC 25922 (MIC=100
CC       uM), Gram-positive bacterium S.epidermidis ATCC 12228 (MIC=100 uM) and
CC       against fungus C.albicans ATCC 24433 (MIC=100 uM) (PubMed:29980138).
CC       Has an anti-inflammatory effect, since it inhibits the production of
CC       the pro-inflammatory cytokines TNF-alpha and IL-1 beta, and induces the
CC       production of the anti-inflammatory cytokine IL-10 (PubMed:30734396).
CC       Has an activity of stimulation of insulin release, which may protect
CC       the species from being eaten by predators by causing fatal hypoglycemia
CC       (PubMed:30734396). Is cytotoxic to cancer line cells (PubMed:30734396).
CC       Shows moderate hemolysis on mouse erythrocytes (LC(50)=75 uM)
CC       (PubMed:30734396). {ECO:0000269|PubMed:29980138,
CC       ECO:0000269|PubMed:30734396}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:29980138}.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin glands.
CC       {ECO:0000305|PubMed:29980138}.
CC   -!- PTM: Phylloseptin-1.2TR is amidated, whereas Phylloseptin-1.3TR is the
CC       name given to the non-amidated form. {ECO:0000305}.
CC   -!- MASS SPECTROMETRY: Mass=1954.2; Method=MALDI; Note=amidated
CC       Phylloseptin-1.2TR.; Evidence={ECO:0000269|PubMed:29980138};
CC   -!- MASS SPECTROMETRY: Mass=1955.2; Method=MALDI; Note=non-amidated
CC       Phylloseptin-1.3TR.; Evidence={ECO:0000269|PubMed:29980138};
CC   -!- SIMILARITY: Belongs to the frog skin active peptide (FSAP) family.
CC       Phylloseptin subfamily. {ECO:0000305}.
