Comments

FUNCTION: Antibacterial peptide, that adopts an alpha helical conformation which can disrupt bacterial membranes. Each caerin displays a different antimicrobial specificity.
SUBCELLULAR LOCATION: Secreted.
TISSUE SPECIFICITY: Expressed by the skin parotoid and/or rostral glands.
MASS SPECTROMETRY: Mass=2340; Method=FAB; Range=1-23; Source=Ref.1;.
SIMILARITY: Belongs to the frog skin active peptide (FSAP) family. Caerin subfamily.
