This family consists of the ocellatin family of antimicrobial peptides. Ocellatins are produced from the electrical-stimulated skin secretions of the South American frog, Leptodactylus ocellatus (Argus frog). The family consists of three structurally related peptides, ocellatin 1, ocellatin 2 and ocellatin 3. These peptides present haemolytic activity against human erythrocytes and are also active against Escherichia coli [PMID: 15648972].
