CC   -!- FUNCTION: Antibacterial peptide, that adopts an alpha helical
CC       conformation which can disrupt bacterial membranes. Each caerin
CC       displays a different antimicrobial specificity.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin dorsal glands.
CC   -!- DOMAIN: Contains two amphipathic alpha helix regions separated by a
CC       region of less-defined helicity and greater flexibility. {ECO:0000250}.
CC   -!- PTM: Caerin-1.7.1 does not have any antibacterial activity.
CC   -!- MASS SPECTROMETRY: [Caerin-1.7]: Mass=2634; Method=FAB;
CC       Evidence={ECO:0000269|PubMed:9204574, ECO:0000269|PubMed:9230483};
CC   -!- MASS SPECTROMETRY: [Caerin-1.7.1]: Mass=2464; Method=FAB;
CC       Evidence={ECO:0000269|PubMed:9204574, ECO:0000269|PubMed:9230483};
CC   -!- SIMILARITY: Belongs to the frog skin active peptide (FSAP) family.
CC       Caerin subfamily. {ECO:0000305}.
