Antimicrobial peptide with activity against Gram-positive bacteria S.epidermidis ATCC 12228 (MIC=50 uM) and S.aureus (MIC=64 ug/ml and MBC=128 ug/ml) (By similarity) (PubMed:29980138). Not active against some Gram-positive bacteria (methicillin-resistant S.aureus (MRSA), E.faecalis), Gram-negative bacterium E.coli ATCC 25922 and fungus C.albicans at concentrations up to 100 uM (By similarity) (PubMed:29980138). Can only slightly inhibit the formation of biofilm by S.aureus (minimal biofilm inhibitionconcentration MBIC=512 ug/ml, minimal biofilm eradication concentration MBEC>512 ug/ml) (By similarity). Has an anti-inflammatory effect, since it inhibits the production of the pro-inflammatory cytokines TNF-alpha and IL-1beta (PubMed:30734396). Has high activity of stimulation of insulin release, which may protect the species from being eaten by predators by causing fatal hypoglycemia (PubMed:30734396). Is not cytotoxic to cancer line cells (PubMed:30734396). Shows very low hemolysis on horse erythrocytes and moderate hemolysis on mouse erythrocytes (By similarity) (PubMed:29980138, PubMed:30734396). Expressed by the skin glands. The primary structure of this peptide is identical to that of Medusin-PT (AC A0A1M4BLT1). Belongs to the frog skin active peptide (FSAP) family. Medusin subfamily.
