Amphipathic alpha-helical antimicrobial peptide with potent activity against Gram-positive bacteria, weak activity against Gram-negative bacteria, and moderate activity against fungi (By similarity). Also displays anti-leishmania activity by damaging parasite membrane (PubMed:25668079). Stimulates insulin release from pancreatic beta-cells in a dose-dependent manner, without increasing intracellular calcium (PubMed:29349894). Protects beta-cells against cytokine-induced apoptosis and augments beta-cells proliferation (PubMed:29349894). In vivo, intraperitoneal injection together with a glucose load into mice does not have effect on plasma glucose levels (PubMed:29349894). Expressed by the skin glands. Belongs to the frog skin active peptide (FSAP) family. Temporin subfamily.
