Antimicrobial peptide with activity against the Gram-positive S.pyogenes (MIC=12.5 uM), but not against all other bacteria tested (both Gram-positive and Gram-negative) (PubMed:23967105). Does not show activity against fungi, and against Leishmania species (PubMed:23967105). Optimum pH is <7. Is active against E.coli ATCC25922 at pH 5 (MIC=50 uM), whereas is not active at pH 7 (MIC>200 uM). Forms a helical membrane channel in the target. Expressed by the skin glands. Belongs to the frog skin active peptide (FSAP) family. Phylloseptin subfamily.
