Amphipathic alpha-helical antimicrobial peptide with activity against Gram-positive bacteria (M.luteus), Gram-negative bacteria (E.coli), and fungi (S.cerevisiae) (PubMed:22439858). Stimulates insulin release from pancreatic beta-cells in a dose-dependent manner, without increasing intracellular calcium (PubMed:29349894). Does not protects BRIN-BD11 beta-cells against cytokine-induced apoptosis (PubMed:29349894). In vivo, intraperitoneal injection together with a glucose load into mice improves glucose tolerance with a concomitant increase in insulin secretion (PubMed:29349894). Expressed by the skin glands. Belongs to the frog skin active peptide (FSAP) family. Temporin subfamily.
