CC   -!- FUNCTION: Antimicrobial peptide with activity against B.cereus,
CC       L.lactis, L.innocua and S.uberis (PubMed:10951191). Probably acts by
CC       disturbing membrane functions with its amphipathic structure
CC       (PubMed:10951191). Inhibits the formation of NO by neuronal nitric
CC       oxide synthase (nNOS) at micromolar concentrations (PubMed:11784303).
CC       Acts by a non-competitive mechanism, probably by binding to
CC       calcium/calmodulin and as a consequence blocking calmodulin attachment
CC       to nNOS (By similarity). {ECO:0000250|UniProtKB:P81835,
CC       ECO:0000269|PubMed:10951191, ECO:0000269|PubMed:11784303}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:10951191}.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin dorsal glands.
CC       {ECO:0000305|PubMed:10951191}.
CC   -!- SIMILARITY: Belongs to the frog skin active peptide (FSAP) family.
CC       Aurein subfamily. {ECO:0000305}.
