Antimicrobial peptide with activity against Gram-negative bacteria but without activity against Gram-positive bacteria (PubMed:16712520). Shows a low activity in stimulating insulin release from rat BRIN-BD11 beta cells, and acts without loss of integrity of the plasma membrane (By similarity). Has very low hemolytic activity (PubMed:16712520). Shows weak amphipathicity in its alpha-helical conformation (PubMed:16712520). Expressed by the skin glands. Belongs to the frog skin active peptide (FSAP) family. Ocellatin subfamily. Ocellatin-L1 may be Ocellatin-L2 without a Asn-23 deamination. Since both peptides do not have the same antibacterial activity, they are kept in two separate entries.
