Antibacterial peptide with moderate activity against the Gram-positive bacteria (S.aureus ATCC 25923, MIC=25 uM), but not against all other bacteria (both Gram-positive and Gram-negative) tested. Does not show activity against fungi, and against Leishmania species (PubMed:23967105). It adopts an alpha-helical structure with very low amphipathicity in membrane environments (Probable). Forms a helical membrane channel in the target. Expressed by the skin glands. The primary structure of this peptide is identical to that of Medusin-PH from Phyllomedusa hypochondrialis (AC L0P402). Belongs to the frog skin active peptide (FSAP) family. Medusin subfamily.
